Question

Isha is 5 year younger than her brother after 4 year their ages will in ratio 2:3 find their present ages

Answer 1

Answer:

Let us consider the age of Isha to be x and the age of her brother to be y

y = x + 5

after 4 years,

age of Isha = x + 4

age of her brother = y+4 = (x + 5) + 4 = x + 9

ratio between both => 2:3

2/3 = (x + 4)/(x + 9)

2(x + 9) = 3(x + 4)

2x + 18 = 3x + 12

18 - 12 = 3x - 2x

x = 6

y = x + 5 = 6+5 = 11

Therefore the age of Isha is 6 and the age of her brother 11.
