Question

10. After five years, Manju's age will be seven less than three times Nisha's age. If Manju is 90 years old
now, then find Nisha's age.
​

Answer 1

Let the age of Nisha be x years

According to question

90+5 = 3x-7

95+7 = 3x

102 = 3x

x = 102/3

x = 34 years

So the age of Nisha is 34 years
