mp (Question:200086.0)

how the value of mp obtained as 150?

Question:
A shopkeeper marks the price of a T.V. set such that he can make 32% profit after giving 12% discount. However a customer availed 20% discount instead of 12%. What is the new profit percentage of shopkeeper?
Options:
A) 20%
B) 44%
C) 30%
D) 35%
Solution:
Ans: (a)




Now, if discount is 20% then

S.P. = MP X (100 - 20) %

S.P. = 150 X 80%

S.P. = 120

\(\therefore\) Profit = 20%


Alternate solution-

Let the CP be 100

\(\therefore\)SP=CP X (100\(\pm\) P/L)

SP=100 X 132%

SP=132

Given discount=12%

\(\therefore\)SP= MP X (100 - D)%

132 = MP X (100 - 12)%

132 = MP X 88%

MP =150


Now, if discount is 20% then

S.P. = MP X (100 - 20) %

S.P. = 150 X 80%

S.P. = 120

\(\therefore\) Profit = 20%
