A shopkeeper mixed 34kg of sugar which costs 22.50 per kg with 29 kg of sugar which costs 15 per kg .at what rate must sell the mixture so as to gain 5% on the total investment?
CP of 34 Kg sugar = 34 x 22.50 = 765 Rs
CP of 29 kg sugar = 29 x 15 = 435 Rs
Total CP = 765+435 = 1200 Rs
and total weight of sugar = 34 + 29 = 63 Kg
Find SP on 5 % gain
SP = (100 + gain %)/100 x CP
= (100 + 5)/100 x 1200 = 1260 Rs
Hence rate must sell the mixture so as to 5 % gain = SP/Total weight of sugar =
1260/63 = 20 Rs/per kg
I hope it is helpful for you....
