A grocer purchased 2 kg . of rice at the rate of Rs. 15 per kg. And 3 kg. of rice at the rate
of Rs. 13 per kg. At what price per kg. should he sell the mixture to earn 33 1/3% profit on

Answer 1

2 KG Rice @ 15/ KG = 30
3 KG Rice @ 13/ KG = 39
TOTAL C.P. = 69
C.P. / KG = 69/5 = 13.8
S.P. for gain of 33% =
$\frac{133}{100} \times 13.8 = 18.4$
