Read Solution (Total 9)
-
- x*105+(1200-x)*111=1200*107
or,x=800 - 6 years agoHelpfull: Yes(13) No(1)
- Total Wheat = 1200Kg
one part is sold at = 5% profit
other part is sold at = 11% profit. So the total profit is 7% of 1200=Rs 84
so we have two parts in 1200 kg
split 1200 into 800 kg and 400 kg
first part is sold at 5% , so 5% of 800 = Rs 40
second part is sold at 11% , so 11% of 400 = Rs 44
first part + second part = Rs 40 + Rs 44
= Rs 84,which is equal to total profit
Therefore 800 Kg of wheat is sold at 5%profit - 6 years agoHelpfull: Yes(8) No(7)
- Let total cost price be 1200.
Let Part of it be x....and given that paert of it is sold at 5% profit so.....selling price=(105/100)*x
Remaining part be 1200-x.... and it is sold at 11% profit....selling price=(111/100)*1200-x
Total 1200kg is sold at 7% profit....so selling price is (107/100)*1200
so total.....=,
((105/100)*x)+((111/100)*1200-x)=(107/100)*1200
by solving this we get 800kg. - 6 years agoHelpfull: Yes(5) No(1)
