### Question 1

What is the value of the first part if 160 is divided in the ratio $3/2$ : $3/2$ : $7/3$?

### Question 2

Two numbers M and N are in ratio 13 : 9. If they are, respectively, increased by 60% and 30%, what will be the new ratio of M : N?

### Question 3

A 350 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**

196 liter.

**B**

197 liter.

**C**

195 liter.

**D**

199 liter.

**Soln.**

**Ans: a**

The volume of milk will remain same at ${78 × 350}/100$ = 273 liters. The amount of water at present is 350 - 273 = 77 liters. We need to make the volume of water equal to that of the milk. So we have to add 273 - 77 = 196 liters of water.

### Question 4

A mixture of milk and water contains 11 parts of milk and 9 parts of water. How much fraction of the mixture should be removed and replaced by water so that ratio of water and milk becomes equal?

**A**

${1/11}$.

**B**

$1{1/5}$.

**C**

$1{10/13}$.

**D**

$2{8/13}$.

**Soln.**

**Ans: a**

Let the volume of the mixture be 11 + 9 = 20 liters. If x liters of the mixture is removed and replaced by water, the volume of water in the new mixture is $9 - {9x}/20 + x$. The volume of the milk in the new mixture would be $11 - {11x}/20.$ Equating the two volumes and solving for x we get x = ${20 × 2}/{2 × 11}$. The fraction that must be removed = $1/20$ × ${20 × 2}/{2 × 11}$, which gives $2/{2 × 11}$ = ${1/11}$.

### Question 5

If 50% of a number is equal to 2/7 of another number, then what is the ratio of first number to second number?
