Question

A vendor buys lemons at Rs 25 per dozen and sells at the rate of 5 for Rs 12 . Find his gain or loss percent

Answer 1

sp of 5 = 12
sp of 1= 12/5
sp of a dozen ie 12 = (12/5)(12)= 144/5
cp of 1dozen = 25= 125/5
gain = (144-125)/5= 19/5
gain %={ (gain)/cp}*100= {(19/5)/(125/5)}*100= (19/125)*100= 76/5= 15.2%

Answer 2

CP of 1 lemon = Rs 25/12
SP of 1 lemon = Rs 12/5
profit = SP - CP
= Rs( 12/5 - 25/12)
= Rs 19/60
profit percent = 19/60× 12/25×100 %
= 76/5 %
