Question

when the fare for a certain journey by an airline was increased in the ratio of 7:6the cost of ticket became 2240find increase in fare

Answer 1

let x be the fare and 2240-x be the increased fare in amount.
then,
x/2240-x = 7/6

6x = 15680-7x
13x= 15680
x= 15680/13
=1206.15
therefore, increase in fare=2240-1206.15
=1033.5
