The line chart given below shows the income and expenditure of a company in five yearn.

The income in year P and Q together is how much percent more than the expenditure in year S and T together?

340 percent

Income of P & Q = 650 + 450 = 1100

Expenditure of S & T = 150 + 100 = 250

Required percentage =  \(\frac{1100 -   250 }{250}\) × 100

=  \(\frac{850}{250}\) × 100

= 340%
