### Question 1

What is x, if 110 : x :: 11 : 9?

### Question 2

The sides of a triangle are in the ratio 3 : 11 : 9, which is the longest side, if the perimeter is 460?

### Question 3

What is the ratio A : B : C if A = $7/12$B and B = $10/3$C?

**A**

35 : 60 : 18.

**B**

7 : 10 : 3.

**C**

12 : 10 : 3.

**D**

7 : 3 : 70.

**Soln.**

**Ans: a**

We can write B = $12/7$A. Now we can use B as the pivot and write $12/7$A = B = $10/3$C. Divide all three with 12 × 10 to get $A/{7 × 10}$ = $B/{12 × 10}$ = $C/{3 × 12}$. So the required ratio is 70 : 120 : 36. The answer is 35 : 60 : 18.
