6)  Ashok bought 16kg of wheat at the rate of Rs 11.50 per kg and 14 kg wheat at rate of Rs 14.50 per kg. He mixed the two and sold the mixture at the rate of 13.50 kg. What is his gain in the transaction?

a) Rs 16                 b) Rs 18                c) Rs 24                 d) Rs 28

Ans: (b)

Cost of 16 kg wheat at Rs 11.50 =  Rs 184.00

Cost of 14 kg wheat at Rs 14.50 =  Rs 203.00

Total cost of 30 kg wheat             =  Rs 387.00

Total sale value of 30 kg at Rs 13.50 = Rs 405.00 Hence the gain is Rs 405 – Rs 387 = Rs 18.00

7) What is the probability of answering a multiple choice question correctly, If you know that one of the answer is definitely wrong but you have to guess between the 3 remaining answers?

a) ¼                        b) ¾                       c) ½                        d) 1/3

Ans: (b)     ( 1 - 1/4 )

8)  What should come in place of question mark (?) in the following number series?

22, 66, 132, 792 , ?
a)      1584             b)      2376            c)      1246             d)      2674

Ans:  (b)

22 * 3 = 66.     66 * 2 = 132.     132 * 6 = 792. The series repeats in this fashion and the next number is

792 * 3 = 2376.

9)  The difference between two numbers is one-seventh of the sum of the two numbers. What is the ratio of the two numbers?

a) 3:4                     b) 4:3                     c) 2:3                     d) 3:2

Ans: (b)

Let the two numbers be ‘x’ and ‘y’ and let us assume (x – y) = 7. Since the difference between the numbers is 1/7 of their total, we have (x + Y) = 49.

Solving the two we get the value of ‘x’ as 28 and ‘y’ as 21. Thus the ratio of the two numbers is 4 : 3

10) On return from a business trip Mr. Chidambaram was to be picked up from the railway station by his coachman. Somehow he managed a train connection earlier and thus arrived two hours early. Immediately on arrival he rang up home for the coach and was told that it had just left in order to be exactly in time for the train by which he was scheduled to come. To save the time he started walking homeward at 3 kmph. On the way he met the coachman who brought him home an hour before schedule. How far is the Mr. Chidambaram’s house from the railway station?

a) 12 Km               b) 15 Km              c) 18 Km               d) 23 Km

Ans: (c)

The train arrived two hours earlier at which time the coachman had started from the house.  Thus the coachman would have taken 2 hours to reach the station and another 2 hours on the return journey totaling in all 4 hours. However he reached home one hour earlier. Hence the coachman had travelled 1.5 hours onward and 1.5 hours return. During this 1.5 hours Mr Chidambaram would have covered 3 * 1.5 -> 4.5 kms.  Let the distance to the station be ‘x’

Then speed of the coachman 2x/4. Thus in 1.5 hours the coach man would have travelled

(2x/4) * 1.5.  This distance equals (x – 4.5) Now equating both we get

(x-4.5) = (2x/4) * 1.5 and we get the value of ‘x’ as 18km.   

11)  A train travelled from Delhi to Patna and back in a certain time at the rate of 60kmph.But if the train had travelled from Delhi to Patna at rate of rate 80Kmph. And back from Patna to Delhi at the rate of 40Kmph. It would take two hours Longer. Find the distance between Delhi and Patna?

a) 480Km             b) 460Km             c) 450Km              d) 465Km

Ans: (a)

Let ‘x’ be the distance between Delhi and Patna. Let ‘t’ be the time it takes to cover both ways going at the speed of 60 kmph.  So we have 2x/60 = t

The total time taken by the train when it travels at 80kmph and 40kmph  is 2 hours more than ‘t’

Thus we have an equation x/80 + x/40 – 2x/60 = 2

Now solving, we get the value of ‘x’ as 480km

12) On a certain pasture the grass grows at an even rate. It knows that 40 cows can graze on it for 40 days before the grass is exhausted, but 30 cows can graze there as long as 60 days. How many would the pasture last if 20 Cows were to graze on it?

a) 140days           b) 100 days         c)110 days           d) 120 days

Ans: (d)

Let I be the initial Grass
      g be the rate of growth of grass per day
      r be the rate of consumption of grass by one cow in one day

For 40 cows
       I+40g=40*40r   -------------------------1
for 30 cows
       I+60g=30*60r   --------------------------2
Then for 20 cows
       I+ng=20*n*r      -------------------------3
                   where n is the no of days

Subtracting the first two equation and dividing it by 20
        g=10r
Subtracting the equations 2 and 3 and  substituting the value of g
we get  value for n=120
