Question

if the cost of 10 greeting cards is equal to the selling price of 8 greeting cards. Then the gain or loss % is

Answer 1

Answer:

Step-by-step explanation:

Cp of 10 greeting cards = Sp of 8 greeting cards

Let cp of 1 greeting card be Rs 1

Therefore, cp of 10 greeting cards = Rs 10

Cp of 10 greeting cards= Sp of 8 greeting cards = Rs 10

Sp of 8 greeting cards= Rs 10

So, sp of 1 greeting card =Rs 10/8

So, Sp is greater than cp,

Therefore, profit = sp-cp = 10/8 - 1 = 10/8-8/8 = 2/8

Profit % = profit/cp into 100 = 2/8 / 1 into 100 = 25%

Answer 2

✬ Gain % = 25% ✬

Step-by-step explanation:

Given:

• Cost Price of 10 greeting cards = Selling Price of 8 greeting cards

To Find:

• What is the gain or loss percent?

Solution: Let the cost price of each card be Rs x.

∴ Cost price of 8 cards = Rs 8x and

• Selling Price of 10 cards = Rs 10x

A/q

• C.P of 8 cards = S.P of 10 cards = Rs 10x

Thus, C.P = Rs 8x and S.P = Rs 10x

Since, S.P > C.P so, there is a profit.

★ Profit = Selling Price – Cost Price ★

$\small\implies{\sf }$ Profit = ( 10x – 8x)

$\small\implies{\sf }$ Profit = ( 10x – 8x)

$\small\implies{\sf }$ Rs 2x

• To find the gain % we use the formula •

★ Gain % = (Gain/C.P) x 100% ★

$\small\implies{\sf }$ Gain % = (2x/8x) (100) %

$\small\implies{\sf }$ Gain % = (2x/8x) (100) %

$\small\implies{\sf }$ Gain % = 25%

Hence, The gain % will be 25%.
