Question

If CP of 25 pens is equal to SP of 30 pens. Find the profit or loss percent?​

Answer 1

Answer:

Suppose the cost price of 1 pen = ₹10, then the cost of 25 pens = 10 × 25 = ₹250, and the selling price = 10 × 30 = ₹300

Now profit = ₹300 - ₹250 = ₹50

Profit% = Profit / Cost Price × 100

= 50/250 × 100 = 2%

Therefore, the profit% is 2%

Answer 2

Answer:

20%

Step-by-step explanation:

Let the C.P of 1 pen be Rs.1

Therefore, C.P of 25 pens = Rs.25

& C.P of 30 pens = Rs.30

Therefore S.P of 25 pens = C.P of 30 pens

= Rs.30

For 25 pens,

C.P = Rs.30

S.P = Rs.25

Therefore loss% = 5 x 100

25

= 20%
