Question

Riya'z mother is 7 times older than him .four years from now, she will be four times as old as Riyaz will then be .What are their present ages ?​

Answer 1

Step-by-step explanation:

Let the age of Riya be = x

Then her mother = 7x

Four years from now,

Riya's age will be 4+x

mother's age will be 4+7x

7x+4= 4(x+4) {Given, she will be four times as old as her age.

Expanding the brackets,

7x+4=4x+16

7x-4x= -4+16

3x = 12

x = 4

~Therefore, Riya's age= 4 years

~ Mother's age= 7x = 7×4=28 years
