Correct Answer - Option 4 : 9.6
Given:
After reduction number is 96
Calculation:
Let assume that original number = x
Reduction in number = 25% of original number
Reduced number = x – 25% of x = 75x/100
According to question
⇒ 75x/100 = 96
⇒ x = 96 × 100/75
⇒ x= 128
Now,
128 × 7.5% = 9.6
7.5% of number is 9.6
The correct option is 4 i.e. 9.6
