Answer:
x = 30
Explanation:
We have to find x
Given that:
20% of x = 12 % of (x +20)
This can be written as:
0.2(x) = 0.12 (x + 20)
0.2x = 0.12x + 2.4
Subtracting 0.12x from both sides we get:
0.2x - 0.12x = 0.12x - 0.12x + 2.4
0.08x = 2.4
Dividing both sides by x we get:
0.08/0.08x = 2.4/0.08
x = 30
