Question

Hidhri is five years more than kawthar.if sum of their age is 36 years find their age

Answer 1

Hidhri is 20 years old

Kawthar is 15 years old

Explanation:

Hidhri is x years old

Kawthar is y years old

x = 5 + y (Hidhri is five years more than Kawthar)

x + y = 36 (sum of their age is 36 years)

Substitute:

(5 + y) + y = 36

5 + y + y = 36

5 + 2y = 36

2y = 36 - 5

2y = 31

y = 31 ÷ 2

y = 15.5

Kawthar is 15 years old.

Since Hidhri is five years more,

15 + 5 = 20

Hidhri is 20 years old.
