Show answer & explanation

Correct answer: B

Explanation

The correct answer is Option 2 i.e. 4% loss.

Given:

discount = 20%

M.P. = 20% above C.P.

Concept Used:

S.P.=M.P.×(100−D)100S.P. = M.P. \times {(100 - D) \over 100}

Profit/Loss% = (S.P.−C.P.)C.P.×100{(S.P. - C.P.)\over C.P.} \times 100

Explanation:

Let the C.P. of the goods be 100.

So, M.P. = 100 + (20%o of 100) = 120

Now, S.P. = 120×(100−20)100120 \times {(100 - 20) \over 100}

⇒ S.P. = 120 × 0.8 = 96

So,  Profit/Loss% = (96−100)100×100{(96 - 100) \over 100} \times 100 = -4

Hence the tradesman made a 4% loss.
