Correct Answer - Option 2 : 240

Given:

12.5% a number is added with itself then the result becomes 270.

Calculation:
12.5% = 12.5/100 = 1/8

Let original number = 8x, number added = 1x

That is, if 100% = 8x then its 12.5%= 1x

Number after addition = 8x + 1x = 9x = 270
⇒ x = 30
Original number = 8x = 8 × 30 = 240

∴ Original number is 240
