Question

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

Answer 1

Cost of 10 bananas = Rs. 45

Cost of 1 banana = $\frac{45}{10} =$ Rs. 4.5

Selling price of 12 bananas = Rs. 51

Selling price of 1 banana = $\frac{51}{12}$ = 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 = $\frac{loss \times 100}{cost \: price}$

⇒ $\frac{0.25 \times 100}{4.5}$

⇒ $\frac{25}{4.5}$

⇒ 5.55%

Hence, The Man has suffered a loss of

5.55 % in Banana.

Answer 2

he had loss because of his thoughts.
