I hope this help you

Answer 2

Find the cost price of the notebooks:

1 dozen = ₹ 156

20 dozen = 156 x 20 = ₹ 3120

Find the selling price of the 8 dozen notebooks:

Gain per dozen = 10% x 156 = 0.1 x 156 = ₹ 15.60

Selling price of a dozen notebooks = 156 + 15.60 = ₹ 171.60

Selling price of 8 dozen notebooks = 171.6 x 8 = ₹ 1372.80

Find the selling price of the remaining 12 dozen:

Gain per dozen = 20% x ₹ 156 = 0.2 x 156 = ₹ 31.20

Selling price per dozen = 156 + 31.20 = ₹ 187.20

Selling price for 12 dozen = 187.20 x 12 = ₹ 2246.40

Total selling price = ₹ 1372.80 + ₹ 2246.40 = ₹ 3619.20

Find the profit gain:

Gain = 3619.20 - 3120 = ₹ 499.20

Gain Percentage = 499.20/3120 x 100 = 16%

Answer: He gain 16% from the transaction.
