Question

Juma's age is twice that of ally.in two years time the sum of their ages will be 40years.find the present age of juma

Answer 1

Answer:

24

Step-by-step explanation:

Lets take Juma's age as J and Ally's age as A.

Given,

J=2A

J+2+A+2=40

Substituting J=2A in equation 2, we get

2A+2+A+2=40

=3A+4=40

=3A=40-4

=3A=36

A=36/3=12

Ally's age is 12.

Juma's age is double of Ally's age that is 12*2=24
