Question

A mixed grain flour is made by mixing 2 Part of mixed grains and three
part of wheat flour. If the mixed grains cost Rs 40 per kg and wheat costs Rs 30 Per kg Find at what Price the mixed grain flour needs to be sold to make a profit of 10%​.

Answer 1

Answer:

Let the quantities of the two types of wheat be 5x kg and 4x kg.

Then, C.P. of the two types of wheat

=5x× Rs. 20+4x× Rs. 25

= Rs. 100x+ Rs. 100x= Rs. 200x

S.P. of the mixture =(5x+4x)× Rs. 24

=9x× Rs. 24= Rs. 216x

S.P. > C.P., then

Profit =216x−200x= Rs. 16x

∴ Profit % =

200x

16x

×100=8%

Here is your answer -

Cost of mixed grains: 40₹/kg

Cost of wheat grains: 30₹/kg

A mixture consist of 2 parts MG amd 3 parts WG

So cost of it will be [(2/5)x40 + (3/5)x30]

Cost = 16+18 = 34₹/kg

For a profit of 10%

%profit = (profit/CP)x100

10 = (X/34)x100

X = 34x10/100 = 3.4₹

SP = Profit + CP = 34+3.4 = 37.4₹/kg
