Two numbers A and B are in the ratio 13 : 17. If A is increased by 15% and B is increased by 30%, then the new ratio of A to B will be:

21 : 29 21 : 31 23 : 34 23 : 33

23 : 34

A : B 13 : 17 A is increased by 15% and B is increased by 30% ⇒ 13 x 115% : 17 x 130% ⇒ 14.95 : 22.1 ⇒ The new ratio of A to B = 23 : 34.
