Question

if the cost price of 5 pens is equal to selling price of 6 pens then find the loss or gain percent​

Answer 1

Step-by-step explanation:

Let the cost price of 1 pencil be ₹1.00

therefore cost price of 6 pencils will be = ₹6.00

As per statement, ₹6.00 is the selling price of 5 pencils

Therefore selling price of 1 pencil is ₹6.00/5 = ₹1.20

We know Profit = selling price - cost price

Thus profit = ₹1.20 - ₹1.00 = ₹0.20

Profit or gain % = profit / cp × 100

Profit or gain = 0.20 / 1.00 × 100

Profit or gain = 20/100 × 100

Profit or gain = 20%

Answer gain percentage will be 20%

Answer 2

Answer:

loss

Step-by-step explanation:

if we take the cost price of 5 pen is x

then per one pen cost is x/5

6 pens are selling same x amount

but here per one pen sell is x/6

which is very less amount than x/5

if those 6 pen sell as per one pen of x/5 then total selling amount would be 6x/5 which is greater amount than x/5

so here we know that one pen is sell as loss

so the loss amount of one pen is

$\frac{ \frac{x}{5} }{x} \times 100 = 20$
