Hallo :)

Let's take Danny's age as n + 4 and his sister as n. You mentioned that the sum of their ages is 36. So, we'll put it in an equation and solve for n.

n + n + 4 = 36
2n + 4 = 36
2n = 36 - 4
2n = 32
%282n%29%2F%282%29 = %2832%29%2F%282%29
n = 16 years old

Since Danny is n + 4
Danny = 16 + 4
= 20 years old

There you go! All the best :) x
