Alligation or Mixture
By mixing two qualities of pulses in the ratio 2: 3 and selling the mixture at the rate of Rs 22 per kilogram, a shopkeeper makes a profit of 10 %. If the cost of the smaller quantity be Rs 14 per kg, the cost per kg of the larger quantity is :
a. Rs 23
b. Rs 24
c. Rs 25
d. None of these
Read Solution (Total 3)
-
- Cost Price of 5 kg = Rs.(14*2 + x*3) = (28 + 3x).
Sell price of 5 kg = Rs. (22x5) = Rs. 110.
[{110 - (28 + 3x)}/(28 + 3x) ]* 100 =10
[82-3x/28 + 3x]= 1 / 10
820 - 30x = 28 +3x
33x = 792
x = 24 - 9 years agoHelpfull: Yes(6) No(0)
- it will be 24
- 9 years agoHelpfull: Yes(0) No(3)
- cost price of the mixture = (22*100)/110 = 20 rs

x-20 : 20 - 14 = 6
as per question ratio is 2:3 or 4 : 6
so x - 20 = 4
x = 24 - 6 years agoHelpfull: Yes(0) No(0)
