# What Must be Added to Each Term of the Ratio 2:5 so that it May Equal to 5:6?

- 65
- 78
- 13
- 12

**Answer: (3) 13**

**Explanation:-
**Let the X be added to each term.

Then, (2 + X)/(5 + X) = 5/6

by cross multiplication,

6 x (2 + X) = 5 x (5 + X)

12 + 6 X = 25 + 5X

6 X – 5X = 25 – 12

X = 13

Then, 13 must be added to each term of the ratio 2: 5 so that it may equal to 5:6.

Hence, the answer is (3) 13.
