Aptitude Questions – 4 (For Bank Exams)

1. Find the reminder when 333666777888999 divided by 3 or 9 or 11?

Ans: Reminder 5 when divided by 11.

Rule of divisibility for 3 and 9 – I f the sum of the digits divisible by 3 or 9 then the whole number is divisible by 3 and 9.

Rule of divisibility for 11 --- If the difference between the sum of the odd placed numbers and even placed numbers is either zero or divisible by 11 then the whole number is divisible by 11.

In this case the difference is 5 and that’s the reminder.

2. Which is the biggest perfect square amongst the following

(a) 15129, (b) 12348, (c) 23716, (d) 20736

Ans: (c)

3. The greatest area of the following:

(a) The radius of circle is 4

(b) The square of diagonal is 4

Ans: (a)

4. The area of the maximum size of the circle inscribed within a 10 inch square?

Ans: 78.57 sq. inch ( The radius of the circle will be half the side of the square)

5. A gold density is 19 times greater than the water and for copper it is 9 times. At

what ratio you can mix gold and copper to get 15 times denser than water?

Ans: 3 : 2

Using the rule of alligation we have for Gold 15 – 9 = 6 parts and for Copper

19 – 15 = 4 parts. Thus the ratio is 3 : 2

6. Find the value of (1.99)2

Ans: 3.9601

7. There is a room with 6' x 8'. A one foot tile is fixed along the 4 walls in one row. How

many more one foot tiles are required to finish the work.

Ans. 24 Tiles

Since all along the wall one foot tile is already fixed, the dimension of the room now is reduced to -> 4 * 6 = 24 sq.ft.

8. Two persons can finish a job in 8 days. First person alone can finish the work in 24

days. How many days does the second person take to finish the job?

Ans: 12 days

Let the two persons be A and B.

A in one day does 1/24 job and B in one day 1/B job.

They both together finish the job in 8 days.

Hence the job done together in one day is 1/8. Thus we have an equation

1/24 + 1/B = 1/8 -> 1/B = 1/8 – 1/24 = 1/12.

1/B = 1/12. B will alone finish the job in 12 days.

9. A person's salary is getting reduced by 20%. What percentage should be added to

get back his original salary?

Ans: 25%

Use the formula ---- 100R/100-R (where R is the percentage of reduction)

10. Two persons start from the same point and walk in opposite directions with 5km/hr and

5.5km/hr speed respectively. What is the distance separating them after 2 and half hrs?

Ans: 26.25 km

Relative speed between the two is ---- 5 + 5.50 = 10.50 km/hr. (They walk in opp.

direction.

Thus the distance between them after 2.30 hours will be 10.50 * 2.30hrs = 26.25 km.

11. A person starts walking at a speed of 5km/hr through half the distance, rest of the distance he covers with a speed 4km/hr. Total time of travel is 9 hours. What is the maximum distance he can cover?

Ans: 40.50 km.

Average speed is ---(5 + 4)/2 = 4.50 km. ( Note: He covers the total distance in two equal half)

Distance/ Speed is = Time. Let X be the distance.

Thus ------ x/4.5 = 9 hrs. solving we get … X = 40.50km

12. Initially two cups of same volume are present with milk filled upto 3/5th and 4/5th

of their volumes. Water is then filled. Then two mixtures are mixed. Find the ratio of water to milk in the mixture.

Ans: 3 : 7

A simple question. Let the volume of the two cups be 5 each. Then total volume is 10. The total volume of Milk in these two cups initially is 3 + 4 = 7parts. The remaining is 3 parts now filled with water.

Thus the ratio of water and milk is ------- 3 : 7.

13. 16 grams of radioactive material decays into 8 grams in 10 years. How long will it

take to decay to 1 gram?

Ans: 70 years.

16 gm reduced to 8gm in 10yrs. So 8 gm get decayed.
For decaying 1 gm it takes 10/8 years. For decaying 8 gm it takes 10/8*8
Remaining 8 gm need to decay 7 to get 1 gm remaining.
For decaying 7 gm it will take
10/8*8*7 = 10*7 = 70 years

14. In a rectangle the length is increased by of the original length. By what proportion

should the width be reduced so that the area will be the same?

Ans: 50%

Assume the original Length and Breadth as 5 and 4. The area is 5 * 4 = 20.

The new length is 5 + 5 = 10. To retain the same area the breadth should be 2.

Breadth reduced from 4 to 2 or 50%.

15. A person’s salary is decreased by steps of 20%, 15% and 10%. What will be the percentage decrease, if the salary is decreased in a single shot?

Ans: 38.8%

Successive percentage change is given by the formula -> x + y + xy/100 where x and y are the two successive percentages.

Applying this after the second decrease, the percentage change is -> -20 - 15 + 300/10 = -32%

After the third decrease the change will be:

-32 – 10 + 320/100 = - 38.8%

1. I have marbles in three different colours as follows:
Blue 60; Green 156; Red 204
I distribute them to children in such a way that each one of them get equal number of marbles and all in one colour.
How many children are there?
(a) 12 (b) 35 (c) 67 (d) 31
Ans: (b)

Find the HCF of 60, 156 and 204. The HCF is 12. Total number of marbles is 420. Divide this by the HCF -> 420/12 = 35.

2. A square of side 6cm has a circle inscribed in it. Calculate the approximate ratio of surface area of the circle to square.
(a) 11/14 (b) 13/14 (c) 12/14 (d) 14/18
Ans: (d)

The area of the Square is 6*6 = 36 sq.cm. The radius of the circle if half the side of the square – 3 cm. The area of the circle is πr² -> 22/7 * 3 * 3 = 28 sq.cm (approx.)

Hence the ratio is 28 : 36 or 14 : 18

3. There are 3 numbers whose ratio is as follows: first: second=2:3 and second : third= 5:8. There sum is 98, what is the second number?
(a) 20 (b) 30 (c) 40 (d) 50
Ans: (b)

Let the three numbers be A, B and C. We now have two ratios

A : B :: 2 : 3 …….. (i) and B : C :: 5 : 8 ……….. (ii)

We have two different values for B in the two ratios. Let us make this common in both the ratios.

Multiply (i) by 5 and (ii) by 3.

We now have one common ratio -> A : B : C :: 10 : 15 : 24

The sum of A + B + C = 98. Hence the value of B is -> 98 * 15/49 = 30.

4. A 30% saline solution is to be converted to a 10% saline solution. How much pure water needs to be added to 100 kg of 30% saline solution?
(a) 150 kg (b) 100 kg (c) 200 kg (d) 250 kg
Ans: (c)

In 100 kg saline solution the salt is 30 kg. This quantum of salt will remain as such in the 10% saline solution also. Since the quantum of salt is 30 kg and its percentage is 10% only the total quantum of solution should be 300 kg.

Hence 200 kg of water needs to be added.

5. In a given factory, average salary combined for the staff and supervisors is Rs 60 while that for only staff is Rs. 56. The average salary of supervisors is Rs. 400. There are a total of 12 supervisors. How many labourers are employed in this factory?
(a) 1020 (b) 1130 (c) 1500 (d) 1532
Ans: (a)

This question can best be answered through Rule of Alligation figure as under.

A (56) B (400)

X (60)

B – X (340) X – A (4)

From the above we observe the ratio of staff and supervisors as 340 : 4

We are informed that there are 12 supervisors.

3 Parts of supervisors amount to 12.

Hence the number of staff is 340 * 3 = 1020.

6. Alok completed a journey from his home to mall in 42 minutes at an average speed of 10kmph. He walked initially at 4kmph and then took an auto which moved at 25kmph. What part of his journey did he walk?
(a) 1km (b) 2km (c) 3km (d) 4km
Ans: (b)
The distance covered in 42 minutes t an average speed of 10 kmph is -> 10 * 42/60 = 7 km.

Let ‘x’ be the distance travelled by walking at a speed of 4 kmph. Then 7-x is the distance travelled by auto at a speed of 25 kmph. We now have an equation:

x/4 + (7-x)/25 = 42/60. Solving we get the value of x as 2 km.

Hence, the distance covered by walking is 2km.

7. Ashish can do 1/4 of his work in 10 days, Vijay 40% in 40 days and Deepak 1/3 in 13 days. Who finishes first?
(a) Ashish (b) Deepak (c) Vijay (d) Can’t say
Ans: (b)

Ashish ……. In 10 days does ¼th work. So, to complete the whole work will take 40 days.

Vijay in 40 days will complete 40% or 2/5 of the work. He will take 100 days to complete the work.

Deepak in 13 days completes 1/3^rd of the work and would take 39 days to complete the whole work.

Hence, Deepak will complete the work first.

8. You can complete a carpet weaving in 10 days while I can do it in 15 days. We work together but I leave in 2 days. How many days will you now require to finish the work?
(a) 7 (b) 8 (c) 19/3 (d) 20/3
Ans: (d)

In one day I will do 1/10 work and my friend will do 1/15 work. Together we both in one day will do 1/10 + 1/15 = 5/30 -> 1/6 work. In two day we both will do 1/6 * 2 = 1/3 work.

The remaining work now is 1 – 1/3 = 2/3 which I alone will have to do.

The time taken by me to complete this work is ----- (2/3) / 1/10 = 20/3 days.

9. Increase in population for a given country in three consecutive years is 10%, 25% and 10%. What is the combined percentage increase for the three years?
(a) 45% (b) 52% (c) 51.25% (d) 45.25%

Ans: (c)

Successive percentage increase for two years is given by the formula -> x + y + xy/100 where x and y are the percentage variation of two successive periods.

Applying this, we get the percentage variation at the end of 2^nd year as -> 10 + 25 + 250/100 = 37.50%

Now the variance between the second and third year is -> 37.50 + 10 + (37.50*10)/100

= 51.25%

10. Sheila and Sunita start a business with investment of Rs8000 and Rs5000 resp. Sunita is an active partner and so she gets 10% of profit separately for supervision. If the total profit is Rs 3240/-, then what is the share of profit for Sunita?
(a) 1445 (b) 1334 (c) 1500 (d) 324
Ans: (a)

Ratio of Shiela and Sunita’s investment are : 8 : 5

10% of total profit of Rs 3240/- is Rs 324/- and this Sunita gets separately.

Remaining profit is --- 3240 – 324 = 2916.

Sunita’s share in this profit is -> 2916 * 5/13 =1121.

Hence, Sunita’s share of profit in the business is ---- 1121 + 324 = 1445.
