Question
When a number is reduced by 25%, the resulting value is
36 more than 60% of the number's initial value. What is the original number?Solution
Let the original number be ‘x’. According to the question, x × 0.75 = 36 + 0.60 × x Or, 0.75x – 0.6x = 36 Or, 0.15x = 36 Or, x = 240 So, the original number = 240
