G = □□ × 2 = 4
B = □□□ group = 4
= 8
320/8 = 40
40 x 3 = 120 boys
40 x 4 = 160 token

Now: Mrs Chopra 5u; son 1u
In 12 yrs: Mrs Chopra 6u; son 2u (hence the value of 1 unit is 12)
So her age now is 60 (12 x 5u), son is 12. To check, in 12 years, she will be 72, son will be 24 (ie she is 3x older than her son)
