The price of pulses has increased by 45%. By what percentage (rounded off to the nearest integer) the increased price of the pulses should be reduced so that the price of the pulses remains unaltered?

Correct option is B

Given:
The price of pulses increased by 45%.
Formula used:
To find the required percentage decrease to return to the original price:
Let the original price be 100 units.
New price after 45% increase = 100 + 45 = 145 units.
Required percentage decrease = ((New Price-Original Price) )/(New Price ) × 100
Solution:
Required percentage decrease = ((145-100) )/145 × 100 =45/145× 100 =31.0345% ≈ 31%
