Question

sonu buys 40 kg of wheat at 12.50 per kg and 30 kg of wheat at 14per kg .at wheat rate per kg should he sell the mixture to gain 5%on the whole.

Answer 1

total money used is 40*12.5+30*14

=500+420

=920

then if he has to gain 5%increment

then amount will be 920*5%

=46

so means there are so many chance according to our will

if we increments the rate of 12.5 rate wheat by .5 then we have 20 rupees

now increments the rate by .86 of 14 rupees rate wheat then we have approx we have 26 more

so 20+26=46 me we gain 5%profit
