Total profit of 17% = 13% from x quintal + 23% from 12-x quintal
Let the cost per quintal is 100.total cost is 1200
1200x 17% = 13% x 100X + 23% x (12-X)100
12x 17 = 13 + 23x12 - 23X
X = 3.69
12-x = 8.3 quintal
Let the cost per quintal is 100.total cost is 1200
1200x 17% = 13% x 100X + 23% x (12-X)100
12x 17 = 13 + 23x12 - 23X
X = 3.69
12-x = 8.3 quintal
