Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 11.8
A person makes a profit of 17% after allowing 10% discount on its marked price i.e
90% of M.P = 117% of C.P
⇒ M.P/C.P = 117%/90% = 39/30
Let M.P and C.P be 39x and 30x respectively,
If he gives 14% discount on the marked price, then his profit percent will be,
S.P = 39x - (14% of 39x) = 39x - 5.46x = 33.54x
Profit % = (3.54/30x) × 100 = 11.8%
