Question

9. A shopkeeper increases the prices by 20% this month. By what percentage the prices
must be reduced so as to bring down the prices back to the original?​

Answer 1

Answer:

Step-by-step explanation:

Price=100

After increase = 120

Reduction to restore

>>(120x100-R/100) = 100

>>100-R=100x100/120

>>100-R=10000/120=83.33

>>R = 16.67%
