1 Answer

Answer :

Since, the profit is 67, so the selling price will be 167% of the cost price

∴Ratio of selling price to cost price will be 5:3

∴Cost price of laddu =30*3/5 = 18

Let cost of flour and sugar is 3s and 7s respectively

Since laddu is made up of flour and sugar in the ratio of 5:3 = (5*3s)+(3*7s)/8=18

15s+21s=144

36s=144

s = 4

∴Price of sugar = 7s = 7 × 4

= Rs. 28
