Question

The ages of A and B are in the ratio 3 :4 six years hence their ages will be in the ratio 4 : 9 the present age of A is?

Answer 1

Answer:

A = 48 , B = 18

Step-by-step explanation:

let coefficient be X,

                                    A=8X

                                     B=3X

after six years,  age will be

                                   A=8x+6

                                    B=3x+6

as per question,

                     (8x+6)/(3x+6)=9/4

                     32x+24=27x+54

                      32x-27x=54-24

                      5x=30

                       X=6

thus putting value of x we have present ages of A and B is 8x=48 and 3x=18
