Given : Two varieties of wheat - A and B costing Rs. 9 per kg and Rs. 15 per kg were mixed in the ratio 3 : 7.
5 kg of the mixture is sold at 25% profit,
To find : the profit made
Solution:
5 kg of the mixture
A : B = 3 : 7
=> A = ( 3/10) 5 = 1.5 kg
B = (7/10) 5 = 3.5 kg
A cost Rs 9 per kg
Cost of 1.5 kg = 9 * 1.5 = Rs 13.5
B cost Rs 15 per kg
Cost of 3.5 kg of B = 15 * 3.5 = Rs 52.5
Total Cost = 52.5 + 13.5 = Rs 66
Profit 25 %
Profit = (25/100) 66 = Rs 16.5
the profit made = Rs 16.5
