Question

Soni's brother is 8year older then 4/5 her age. If her brother's age is 32 years , what is soni's age?

Answer 1

Answer:

Soni's age = 30 years

Step-by-step explanation:

Let Soni's age = x

Given that Soni's brother's age = 32

Hence

32 = 8 + (4/5)*x

4x/5 + 8 = 32

(4x + 40)/5 = 32

4x + 40 = 160

4x = 160 - 40

4x = 120

x = 30

Soni's age = 30 years

Verification:

4/5 of Soni's age = 4/5*30 = 24

Add 8 years, you get 32, which is Soni's brother age as given in the sum.

Answer 2

Answer:

x=30

Step-by-step explanation:

Let soni's age be x

Brother's age=4/5x+8=32

4/5x=32-8

4/5x=24

4x=24x5

x=6x5

x=30
