Question

The sum of ages of 4 girls born at the intervals of 5 years each is 98 years. What is the youngest...

Answer 1

Hey, there!

Here's the answer you are looking for.

Let the age of the youngest child be 'a' yrs

So, the rest of the older children are (a+5), (a+10) & (a+15)

Sum = a + a + 5 + a + 10 + a + 15 = 98

=> 4a + 30 = 98

=> 4a = 68

=> a = 68/4 = 17 yrs.


Thus, the youngest one is 17yrs old.


Hope that helps!

Thanks.
