Question

the price of an article is reduced by 25% in order to retain the original price by what percentage should the present price be increased?Please explain it.​

Answer 1

Answer:

33.33%

Explanation:

original price : ₹100

reduced : 25%

new price : 100-25 = ₹75

now...

increase ₹75 by 100

i,e..75 + x% of 75 = 100

x% of 75 = 100-75

x% of 75 = 25

(x/100) × 75 = 25

x = 25 × 100 /75

x ~ 33.33%

hence it should be increased by 33.33%
