Question

A shopkeeper has 30 kgs of wheat, a part of
which he sells at 16% profit and the rest at
6% profit. He gains 10% on the whole quantity.
Find the quantity sold at 6% profit.​

Answer 1

Answer:

he sold 25•2 kgs at 6%

Step-by-step explanation:

total amount of wheat the shopkeeper had=30 kgs

profit in % for the first part=16%

profit in % for the second part=6%

profit in % for the entire quantity of wheat=10%

let the first part be x

let the second part be y

therefore x+y=30 kgs

therefore x/30 ×100=16

x=16×30/100

x=480/100

x=4.8 kgs

y=30-x... (since x+y=30)

y=30•0-4•8

y=25•2 kgs
