### Question 1

What is 304 × 25?

### Question 2

A piece of length $16{3/38}$ is cut out of a pipe of length $38{3/16}$. What is the length of the remaining pipe?

**A**

$22{33/304}$.

**B**

$23{56/303}$.

**C**

$20{33/34}$.

**D**

$24{17/18}$.

**Soln.**

**Ans: a**

We have to find $38{3/16}$ - $16{3/38}$, which is same as ${611/16}$ - ${611/38}$ = 611 × ${38 - 16}/{38 × 16}$ = ${6721/304}$. So ${6721/304}$, which is same as: $22{33/304}$ is the required answer.

### Question 3

What is 277 × 9?

**A**

2493.

**B**

2502.

**C**

2484.

**D**

2511.

**Soln.**

**Ans: a**

This is a multiplication by 9. Proceed like this: 277 × 9 = 277 × (10 - 1) = 277 × 10 - 277 = 2770 - 277 = 2493. Sometimes, the options can be ruled out by examining the units places, but for simpler cases these shortcuts will help you save time overall.

### Question 4

Mr. X and Mr. Y have certain number of marbles with them. If Mr. X gives 2 marbles to Mr. Y, they will have the same number of marbles. But, if Mr. Y gives 4 marbles to Mr. X, then Mr. X will have twice as many marbles as are left with Mr. Y. How many marbles does Y have?

### Question 5

A piece of length $13{1/11}$ is cut out of a pipe of length $33{3/13}$. What is the length of the remaining pipe?

**A**

$20{20/143}$.

**B**

$21{41/142}$.

**C**

$18{127/145}$.

**D**

$22{119/145}$.

**Soln.**

**Ans: a**

We have to find $33{3/13}$ - $13{1/11}$, which is same as ${432/13}$ - ${144/11}$ = 432 × ${11 - 13}/{11 × 13}$ = ${2880/143}$. So ${2880/143}$, which is same as: $20{20/143}$ is the required answer.
