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?

Answer»

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 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.
