5.70 per kg to produce a mixture
worth ` 6.30 per kg, is

Answer 1

CP of unit quantity of 1st kind = 7.20 rs/kg =720 paise

CP of unit quantity of 2nd kind is =5.70 rs/kg =570 paise

The mean price is 6.30 rs/kg =630 paise

The ratio should be (mean price- 2nd unit price) = (630-570) : (1st unit price - mean price) = (720-630)

Which is 60:90=2:3

So the answer is the rice of 7.2rs/kg and 5.7rs/kg should be mixed at 2:3 ratio to produce a mixture of 6.3 rs/kg
