Question

Bus fare was increased by 16% and thus number of passengers decreased by 8%. find the % change in the income.​

Answer 1

Answer:

67.2%

Explanation:

let the initial bus fare be 100

income by 10 passengers =100 ×10=1000

when bus fare increases by 16%= 116

number of passenger decrease by 8%

=8×10/100

=0.8

thus passengers=10-0.8

9.2

income now=116×9.2

1067.2

difference in income =1067.2-1000

=67.2

%change in income= (x×100)/100=67.2

x=67.2%
