When a number is increased by 8, it becomes 120% of itself. Find the number.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 40.
Let the original number be x
According to the given condition, when the number is increased by 8, it becomes 120% of itself.
⇒ x + 8 = 120% of x
⇒ x + 8 = 120/100 × x
⇒ x + 8 = 1.2x
⇒ 1.2x - x = 8
⇒ 0.2x = 8
⇒ x = 40
Thus, the number is 40
