Question

a man bought banana at the rate of 10 for 45 and sold at the rate of 1 banana for rupees 51 find his gain or loss percent

Answer 1

45 bananas brought at the rate of 10
sold at the rate of 51 for 1 banana.
therefore profit = sp-cp
sp = 51x45 and cp=10x45
p= 51*45 - 10x45
= 2295 - 450
= 1845.
p% = p/cp x 100
1845/ 450 x 100
410%

Answer 2

45 bananas cost price = RS 10
1 bananas selling price = RS 51
45 bananas price =51×45=2295 RS
therefore gain =SP>CP
=2295-10=2285 RS
gain %=SP/CP %
