Question

Alvin sold an item to Brandon at a profit of 20% and Brandon sold the

same to Christopher at a profit of 15%. If Brandon obtained a profit of

Rupees 72, then the profit obtained by Alvin​

Answer 1

Answer:

80

Step-by-step explanation:

Let the item's original price be 'x'

Alvin's profit percent = 20%

Brandon's profit percent and profit respectively = 15% and 72

72 = 15% of [ 120 x/100]

72 = 15/100 * 120 x/100

72 = [120 x/100] *15%/100

=> 18 x = 72

x = 400

20% of 400 = 80

∴ The profit obtained by Alvin = 80
