Aruna's age find the present age of Aruna.​

Answer 1

Answer:

now the age of Arun is 14yr

Answer 2

Step-by-step explanation:

Let Aruna's age is x

and her Mom's age is y

so now

x +y = 49

7 years ago their ages were x-7

and y-7

Given that 7 years ago

y - 7 = (x - 7) × 4

y - 7 = 4x - 28

y = 4x - 21

put this value in

x + y = 49

x + 4x - 21 = 49

5x = 49+21

x = 70/5

x = 14 years

now current age of Aruna is 14 years .
