The difference between the value of the number increased by 20% and the value of the number decreased by 25% is 36. Find the number ?

Answer: Option D

Let the number = x
According to the question,
⇒ x × $$\frac{120}{100}$$ - x × $$\frac{75}{100}$$ = 36
⇒ 120x - 75x = 3600
⇒ 45x = 3600
⇒ x = $$\frac{3600}{45}$$
⇒ x = 80
Hence, required number = 80
