Question

Two numbers A and B are in ratio 15 : 11. If they are both increased by 40%, what will be the new ratio of A : B?

A

$1{4/11}$.

B

$2{3/5}$.

C

${4/13}$.

D

$3{9/13}$.

Soln.
Ans: a

New A will scale to $140/100$ × 15, and B to $140/100$ × 11. New ratio is ${140 × 15}/{140 × 11}$ = ${15/11}$, which is same as: $1{4/11}$.
