Answer 1

Hlo mate!!


c.p. of 1 pen=Rs n (given each)
so c.p. of m pens=rs mn

s.p. of 1 pen =rs m
so s.p. of n pens=rs mn
so profit =s.p.-c.p.=0(zero)


Hope it helpful

Answer 2

Answer:

Profit is Rs.0 and profit percentage is 0 %

Step-by-step explanation:

Given,

Cost price of one pen = n

According to question,

He bought m pens

So,

Total CP = m * n = mn

Also,

Selling price of one pen = m

He sold n pens

So,

Total SP = n * m = nm

Since we knoeu,

Profit = SP - CP

Profit = mn - mn = 0

Therefore,

Profit percentage will also be 0%

Hence,

Profit is Rs. 0
