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.
