### Question 1

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.

### Question 2

What is the ratio A : B : C if A = $6/5$B and B = $15/4$C?

**A**

18 : 15 : 4.

**B**

6 : 15 : 4.

**C**

5 : 15 : 4.

**D**

6 : 4 : 90.

**Soln.**

**Ans: a**

We can write B = $5/6$A. Now we can use B as the pivot and write $5/6$A = B = $15/4$C. Divide all three with 5 × 15 to get $A/{6 × 15}$ = $B/{5 × 15}$ = $C/{4 × 5}$. So the required ratio is 90 : 75 : 20. The answer is 18 : 15 : 4.

### Question 3

The sides of a triangle are in the ratio 4 : 6 : 3, which is the longest side, if the perimeter is 260?

### Question 4

If X is 40% more than Z, and Y is 30% more than Z, what is the ratio of X to Y?

### Question 5

What is the value of the first part if 142 is divided in the ratio $7/2$ : $6/7$ : $5/7$?
