Question

10 years ago A was 1/3 rd of Q's age of the ratio of their present ages of A and Q is 4:7 what is total sum of their ages after 5 years​

Answer 1

Answer:

54

Step-by-step explanation:

Solved using ratio method

10 years ago A was 1/3rd of Q's age

so ratio = 1:3

present age ratio = 4:7

make two ratio's equal

(1:3)*3 = 3:9

(4:7)*2= 8:14

8-3=14-9=5 units = 10 years

1 unit = 2 years

so the ages of A and B are 2*8 = 16 and 2*14 = 28

after 5 ages their ages become 21 and 33

sum = 21+33 = 54
