Question

a person sells 36 oreanges per rupee and suffers a loss of 4%.how many oranges per rupee to be sold to have a gain of 8%?

Answer 1

S.P OF 1 ORANGE= 1/36 RS.

C.P OF 1 ORANGE= (1/36) * (100/96) RS.

TO GET A GAIN OF 8% S.P OF ONE ORANGE SHOULD BE= (1/36) * (100/96) * (108/100) = 1/32 RS.

THEREFORE, TO GET A GAIN OF 8%, 32 ORANGES NEED TO BE SOLD PER RUPEE

Answer 2

A man sells 36 orenges per rupee and suffers a loss of 4% so actual price of the orenges wer e-therefore
$x - (x \times 4 \div 100) = 1 \div 36$
$x - x \div 25 = 1 \div 36$
$24x \div 25 = 1 \div 36$
$864x = 25$
$x = 25 \div 864$
the price of each piece of oranges were 25/864
