Question
Anita bought 80 pencils for Rs. 96 and she sold them in
such a manner so that selling price of 40 pencils is Rs. 72. Find the value of 2(P + 10) if the profit percent earned by Anita is 'P%'.Solution
ATQ, Cost price of 1 pencil = (96/80)= Rs. 1.20 Selling price of 1 pencil = 72/40 = Rs. 1.80 Profit earned = 1.80−1.20=Rs. 0.60 So, 'P' = (0.60/1.20)×100 = 50% P = 50 Required value = 2×(50+10) = 2×60 = 120
