Question

Find the quantity of rice @ 10 per kg which should be mixed with 25 kg of rice @ 8 per kg so that on selling the mixture @ rs 15 per kg there is 80% profit

Answer 1

Let X kg of Rs10/kg rice should be mixed to 25kg of Rs. 8/kg

CP of (25+X)Kg =10X+200

SP .........=15(25+X) =375 +15X

Profit = (375 +15X) -(10X+200)

======175+5X

ATQ

(175+5X) /(10X+200 ) × 100 =80

875+25X =40X+800

15X= 75

X= 75/15=5

X=5 kg

5 kg of Rs 10/Kg
