Answer 1

Given⤵️

•Average age of Asha, Usha and Nisha is 25 years.

•The sum of Usha's and Nisha's age is four times that of Asha's age.

To Find⤵️

Asha's age

Solution ⤵️

Average age = 25 ...(given)

From the given condition,

Average age = Asha +Usha + Nisha/3=25

∴ Asha + usha + nisha=25 * 3 = 125

Now let the age of Asha be x,

∴x + 4x = 125

∴5x = 125

∴ x= 125/5

∴ x= 25

∴ Therefore Asha's age is 25 years
