The demand function of a light rail transit system (LRTS) of a city is represented as \(Q = 43000 - 850P\), where \(Q\) is the ridership/day and \(P\) is the fare/ride. If the existing fare of Rs. 30 per ride is reduced to Rs. 25 per ride, then the consequent increased ridership of the LRTS (in percentage) is (rounded off to two decimal places).
