When a number is increased by 40, it becomes 125% of itself. What is the number?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 160
Becoming 125% of itself means the number has grown by 25% of itself (125% − 100%), and that growth is the 40 that was added.
25% of the number, that is, one quarter of it, is 40
So the whole number is four times 40: \(40\times4=160\)
