A number when decreased by 12.5% becomes 119. The number is (A) 130 (B) 125 (C) 148 (D) 136

Correct option is D

​

Let the original number be x. According to the problem, when the number is decreased by 12.5%, it becomes 119.

• 12.5% decrease means the remaining value is (100 - 12.5) = 87.5% of the original number.
• Mathematically,
  ​$$x \times \frac{87.5}{100} = 119$$​​
  
• Solving for x:$$x = \frac{119 \times 100}{87.5}$$
• $$x = \frac{11900}{87.5} = 136$$​​​

Thus, the correct answer is (D) 136.
