1.	A vendor purchased bananas at ₹40 per dozen and sold them at 10 for ₹36. Find the gain or loss percent. Hint: let the number of bananas bought be LCM (12, 10) = 60
Answer» We know that the SP of 10 bananas = ₹36 SP of 1 banana = ₹36/10 = ₹3.6 SP of 1 dozen bananas = ₹3.6 × 12 = ₹43.20 CP of 1 dozen bananas = ₹40 Since, SP is more than CP so it’s a gain. Gain = SP – CP = 43.20 – 40 = ₹3.2 Gain % = (3.2 × 100) / 40 =8% ∴ The Gain percent is 8%

A vendor purchased bananas at ₹40 per dozen and sold them at 10 for ₹36. Find the gain or loss percent. Hint: let the number of bananas bought be LCM (12, 10) = 60

Answer»

We know that the SP of 10 bananas = ₹36

SP of 1 banana = ₹36/10 = ₹3.6

SP of 1 dozen bananas = ₹3.6 × 12 = ₹43.20

CP of 1 dozen bananas = ₹40

Since, SP is more than CP so it’s a gain.

Gain = SP – CP = 43.20 – 40 = ₹3.2

Gain % = (3.2 × 100) / 40

=8%

∴ The Gain percent is 8%
