Question

The price of rice has been increased by 40? by how much percent must this new price be decreased to retain its former price?

Answer 1

Dear student,
let the initial price be RS. 100
After increment of 40% price = 100+ (40/100)*100 = Rs. 140
Now decrement to regain its price = 140-100 = Rs. 40
So % decrement of price = (40/140)*100 = 28.57 %
