Question

2. A number is decreased by 25 %. By what percentage should the resultant number be
increased to get
the initial number? Round off your answer to two decimal places.

Answer 1

Answer:

33.33 %

Step-by-step explanation:

Let us consider the number to be 100.

25% of 100 = 25

100 - 25 = 75

To get 100 again, 75 must be increased by 25. To derive our answer, we need to find the percentage of 25 out of 75.

⇒ (25/75 * 100)%

⇒ (1/3 * 100)%

= 33.3333% ≈ 33.33%

Hence, the resultant number must be increased by 33.33% to get the initial number.
