If by increasing the price of a ticket in the ratio 8 : 11 the number of tickets sold fall in the ratio 23 : 21 then what is the increase (in Rs.) in revenue if revenue before increase in price of ticket was Rs. 36,800?1). 212502). 94003). 78504). 12850

Answer»

Let the price of the ticket be 8x and revised price be 11x (SINCE the ratio given is 8 ? 11)

Number of tickets sold be 23y and revised number be 21Y,

⇒ Revenue before increase in price = 8x × 23y = 184xy

⇒ Revenue after increase in price = 11x × 21y = 231xy

Given, 184xy = 36800

XY = 200

INCREASED revenue = 231xy = 231 × 200 = Rs. 46200

∴ Increase in revenue = 46200 - 36800 = Rs. 9400
