Question

chioma is older than chidi by 5 years three years ago,the ratio of their ages was 5:3, find the present age of chidi​

Answer 1

18

Explanation:

The ratio of their ages was 5:3.

5 would be Chioma's age (because its greater) and 3 would be Chidi's age.

However, they are only 2 spaces apart and not 5, so keep adding multiples of the numbers until it gets to 5.

5:3

10:6

15:9

20:15

20:15 is the first one that was 5 years apart, so those must've been their ages three years ago.

Chidi would've been 15 years old, so adding 3 years to it to get to the present age, Chidi would be 18.
