A man bought bananas at the rate of 10 for 45 and sold at the rate of one dozenbananas for 51. Find his gain or loss per cent.

Answer»

Cost price of 10 bananas CP = Rs 45

Now,Selling price of one dozen or 12 bananas = Rs 51

Then,Selling price of 10 bananas SP= (51/12)*10= 51*5/6= 255/6 = 42.5

Therefore, Loss% = (CP - SP/CP)*100 = [(45 - 42.5)/45]*100 = 2.5*100/45 = 250/45 = 5.5 %

an bought bananas at the rate of 10 for45 and sold at the rate of one dozenas for51. Find his galn or loss per cent. .

Answer»

Cost of 10 bananas = Rs. 45

Cost of 1 banana = 45/10

= Rs. 4.5

Selling price of 12 bananas = Rs. 51

Selling price of 1 banana = 51/12

= Rs. 4.25

Loss = Cost price of 1 banana- Selling price of 1 banana

Loss = 4.5 - 4.25

Loss = Rs. 0.25

Loss percent = (Loss*100)/Cost price

⇒ (0.25*100)/4.5

⇒ 25/4.5

⇒ 5.55%

So, he suffered a loss of 5.55 %.
