Correct Answer - Option 3 : 264
Given:
A number is increased by 12.5%
Calculation:
12.5% = 12.5/100 = 1/8
We take original number = 8x,
Thus, if increased by 12.5%, number becomes 8x + 1x = 9x
Also, given new number = 297
⇒ 9x = 297
⇒ x = 33
Also, New number : original number = 9x : 8x
Thus, original number = 8x = 8 × 33 = 264
∴ The original number is 264
