If 60% of a number is 120, what is 20% of that number?
A20
B40
C60
D80
Explanation
- Find the number first: 0.6x = 120, so x = 120 ÷ 0.6 = 200.
- Now take 20% of 200, which gives 40.
- Faster route: 20% is one third of 60%, so the answer is simply 120 ÷ 3 = 40.
- Option D 80 is what you get by taking 40% of the number instead of 20%.
- Once you know 10% of the number is 20, every other percentage is just a multiple of that.
