Question
Sakshi purchased 36 chocolates for a total of Rs. 45.
She then sold 24 of these chocolates for Rs. 39. If Sakshi's profit percentage from this transaction is represented as 'P%', calculate the value of 3(P + 20).Solution
Cost price of 1 chocolate = (45/36) = Rs. 1.25 Selling price of 1 chocolate = (39/24) = Rs. 1.625 Profit earned = 1.625 - 1.25 = Rs. 0.375 So, 'P' = (0.375/1.25) X 100 = 30% Or, P = 30 Required value = 3 X (30 + 20) = 150
