Question

Jumoke is 11years older than amina. in 5 years time, jumoke will be twice as old as amina. Find amina present age​

Answer 1

Answer: 3

Explanation:

In 5 years, Jumoke will be 16. 16 divided by 2 is 8. Amina will be 8 in 5 years. If we subtract 5 from 8, we see that Amina is 3 currently.

Answer 2

6 years old

Explanation:

Suppose Amina's age is "a" and Jumoke's age is "j". We know that Jumoke is 11 years older than Amina, so we can say: j = a + 11

In 5 years' time, Jumoke will be twice as old as Amina then. In 5 years, Jumoke will be j + 5 years old, and Amina will be a + 5 years old. Since Jumoke will be twice as old then, the equation is: j + 5 = 2 * (a + 5)

We can substitute a + 11 in for j in the second equation:

(a + 11) + 5 = 2 * (a + 5) = 2a + 10

a + 16 = 2a + 10

a = 6

Thus, Amina's present age is 6 years old.

Hope this helps!
