Question

the ratio between the present ages of P&R is 5:3.the ratio between P's age of four years ago and R's age four years hence is 1:1.what is the ratio between P's age 4 years hence and R's age 4 years ago?​

Answer 1

Answer:

3 : 1

Step-by-step explanation:

present age of P : present age of R = 5 : 3

let, P's present age = 5x and R's present age = 3x

atq,     (5x - 4) : (3x + 4) = 1 : 1

    or,   5x - 4 = 3x +4

    or,   2x = 8  or, x = 4

present age of P = 5 x 4 = 20 and R = 3 x 4 = 12

P's age 4 years hence = 20 + 4 =24

R's age 4 years ago = 12 - 4 = 8

the required ratio = 24 : 8 =3 : 1
