Question

help me................................

Answer 1

Step-by-step explanation:

Given, Cost price of 5 bananas = 4.

Then, Cost price of 1 banana = (4/5).

Given, Selling price of 4 banana = 5.

Then, Selling price of 1 banana = (5/4).

Here, Selling price > Cost price. So, Gain has occurred.

(a)

Gain = Selling price - Cost price

        = (5/4) - (4/5)

        = 9/20

Gain% = (Gain/CP) * 100

          = (9/20)/(4/5) * 100

          = 56.25%.

Therefore, Gain percent = 56.25%

(b)

Gain Per banana = (5/4) - (4/5) = 9/20.

Total profit to be earned = 45.

Number of bananas to be sold = (45)/9/20

                                                   = 900/9

                                                   = 100.

Therefore, he should sell 100 bananas.

Hope it helps!

Answer 2

Given, Cost price of 5 bananas = 4.

Then, Cost price of 1 banana = (4/5).

Given, Selling price of 4 banana = 5.

Then, Selling price of 1 banana = (5/4).

Here, Selling price > Cost price. So, Gain has occurred.

(a)

Gain = Selling price - Cost price

        = (5/4) - (4/5)

        = 9/20

Gain% = (Gain/CP) * 100

          = (9/20)/(4/5) * 100

          = 56.25%.

Therefore, Gain percent = 56.25%
