1. (b) 2. (a) 3. (c) 4. (b) 5. (b) 6. (d) 7. (a) 8. (d) 9. (c) 10. (b)

Explanation

1. (B) Assume that milkman purchased 6 litres of milk and one litre of milk costs 1 rupee. So CP= Rs.6

He sells it for Rs.2 then his SP= Rs.12. also he is adding 2 litre of water so 2 litre gains an amount of Rs.4.

2. (A)

The car starts at first pole and reaches 12th pole within 24 seconds.

To find the time taken by a car,

Time to cross a single pole=

Time to cross a 20 poles= 19×2.182=41.45

3. (C) We know that

Sum of natural numbers= (N(N+1))/2

We don’t know the value of N. So substitute some value and find the value of N. If we take N as 50 then the Sum will be 1275.  Sum is larger than 1000. So we can’t take it.Then go for 45 then the sum is 1035. So go for 44 then the sum will be 990.

So if we add 10 twice then the sum will be 1000. So 10 is the answer.

4. (B) Let the amount borrowed for 5% is X then

For 7% = 2500-X

Now I1+ I2= 275

By solving,

X = 1875

For 7% rate, sum = 2500-1875  = 625

5. (B)

Cistern fill in 6 hours.

Part of the cistern is emptied due to leakage in 1 hour

So the leak can empty the cistern in 24 hours.

6. (D)

Let the number of papers be X. Then 63X+ 20 + 2 = 65X.

Then X= 11.

Alternate way.

Due to the Extra mark of 22, average increases by 2. So by dividing 22/2 we can get 11 as a answer.

7. (A) Because we are taking man as a reference there is no need to take the first train length.

8. (D)

9. (C) Let the income in 1995 of company A and Investment of company B in 1996 be x.

Then

10. (B)

Income of company B in 1993
