Question

The present age of Nisha’s mother is three times that of Nisha’s. After five years, sum of their ages would be 70 years. Find their present ages.​

Answer 1

Answer:

let nisha's present age = x years

mother's present age = y years

3x = y

after 5 years.

(x + 5) + ( y + 5)= 70

since y = 3x

4x = 60

x = 15

y = 3* 15

y = 45

there fore nisha's present age is 15 years and mother's present age is 45 Years

Answer 2

Answer:

Nisha is 15, Nisha's mother is 45

Step-by-step explanation:

Let Nisha be N.

Nisha's mother is 3N

After 5 years: (N+5)+(3N+5)=70

4N+10=70

4N=60

N=15

3N=45
