Answer:
6 years old
Step-by-step 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!
