Question

The ratio between the present age of P and Q

is 3 : 4 respectively. Four year hence Q will be 5

years older than P. What is P’s Present age?​

Answer 1

Answer:

x=5. So, now p's present age is 3x that is 3×5=15. So, their ages after 5yrs are p= 15+5=20 and q=20+5=25. So, the ratio of their ages after 5yrs is 20:25, that is 4:5
