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

• 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

• 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
