Question

2. The ratio of present ages of A and B is
4:3. If four years before, the ratio of
their ages was 2:1, the present age of A
is?​

Answer 1

Step-by-step explanation:

A/B=4x/3x

before 4 years 4x-4/3x-4=2/1

4x-4=6x-8

6x-4x=-4+8

2x=4

x=2

present age of a is 4x=4×2=8

present age of B is 3x=3×2=6
