Question

I bought 80kg of wheat for rs.66 and was obliged to sell it at a loss of as much money as i receive for rs.20kg.At what price did i sell the wheat?.

Answer 1

CP=80 × 66 = 5280

LET SP FOR 20 KG WHEAT BE X

SO LOSS IS X

SP FOR 80 KG WHEAT = 4X

loss per cent = X/100

SP=100-X/100 /100 ×5280

$((100 - x \div 100) \div 100) \times 5280$

and you will get answer
