Download Solution PDFGiven:
A vendor sold 5 chocolates for ₹1, gaining 20%.
Formula used:
Selling Price (SP) of 1 chocolate = ₹1/5
Cost Price (CP) of 1 chocolate = SP ÷ (1 + Gain%)
Number of chocolates bought for ₹1 = ₹1 ÷ CP
Calculation:
Selling Price (SP) of 1 chocolate = ₹1/5 = ₹0.2
CP of 1 chocolate = SP ÷ (1 + Gain%)
⇒ CP = 0.2 ÷ (1 + 20/100)
⇒ CP = 0.2 ÷ 1.2
⇒ CP = ₹0.1667
Number of chocolates bought for ₹1 = ₹1 ÷ ₹0.1667
⇒ Number of chocolates = 6
∴ The correct answer is option (2).
