How many kgs of Basmati rice costing Rs.42/kg should a shopkeeper mix with 25 kgs of ordinary rice costing Rs.24 per kg so that he makes a profit of 25% on selling the mixture at Rs.40/kg?
As the trader makes 25% profit by selling the mixture at Rs.40/kg, his cost per kg of the mixture = Rs.32/kg.
C.P of 1 kg of rice of 1st kind = Rs. 42
C.P of 1 kg of rice of 2nd kind = Rs. 24
Mean price = Rs. 40
By the rule of Alligation, we have:
C.P. of 1kg of C.P. of 1kg of
rice of 1st rice of 2nd
kind (Rs. 42) kind (Rs. 24)
40 - 24 : 42 - 32
Let the amount of Basmati rice being mixed be x kgs
8 : 10 = x : 25
4/5 = x/25
x = 25 kgs.
Hence, option 4 is the correct answer.
