### Question 1

If 50% of a number is equal to 9/13 of another number, then what is the ratio of first number to second number?

**A**

$1{5/13}$.

**B**

$2{7/12}$.

**C**

${1/3}$.

**D**

$3{4/5}$.

**Soln.**

**Ans: a**

We have ${50A}/100 = {9B}/13$, which can be re-arranged to $A/{9 × 100} = B/{50 × 13}$, so the required ratio is (9 × 100) : (50 × 13), which is 18 : 13. So the answer is ${18/13}$, which is same as: $1{5/13}$.

### Question 2

Two numbers are in the ratio 18 : 5. If both are increased by 8, the new ratio becomes 19 : 6. What is the first number?

### Question 3

Two numbers M and N are in ratio 17 : 19. If they are, respectively, increased by 40% and 20%, what will be the new ratio of M : N?

### Question 4

Two numbers A and B are in ratio 8 : 9. If they are both increased by 10%, what will be the new ratio of A : B?

### Question 5

A 250 liter mixture of milk and water contains 78% milk. How many more liters of water should be added so that the proportions of milk and water become equal?

**A**

140 liter.

**B**

141 liter.

**C**

139 liter.

**D**

143 liter.

**Soln.**

**Ans: a**

The volume of milk will remain same at ${78 × 250}/100$ = 195 liters. The amount of water at present is 250 - 195 = 55 liters. We need to make the volume of water equal to that of the milk. So we have to add 195 - 55 = 140 liters of water.
