Question

The railway face increased by 20% . Again after a month it increased by 10%. What is the percentage increase in the original fare?

Answer 1

10% has been increased
20%-10%=10%
Because after 1 month they asked

Answer 2

Let the fare be = 100

Increased by 20% means = 100 + (100 ×20 / 1000 = 120

Again increased by 10 %  = 120 + (120 × 10 / 100 ) = 132

So to get back the original fare of 100 = we reduce 132 to 100

% of reduction =(132 - 100 / 132 ) ×100 = 56.24

Ans:-The percentage increase in the original fare is 56.24%
