A dealer allows his customer a discount of 25% and still gains 25%. If cost price of a radio is Rs. 1440, its marked price is:
A. Rs. 2500
B. Rs. 2440
C. Rs. 2400
D. Rs. 2020
Answer: Option C
Solution (By Examveda Team)
Let MP = X CP = 1440 SP = 1440 + 25% of 1440 = Rs. 1800 SP = MP - 25% of MP SP = X - 25% of 100 SP = X - 0.25X 1800 = 0.75X X = 2400 MP = Rs. 2400 Short-Cut Let the marked price = Rs. x Hence, $$\frac{{{\text{75}} \times {\text{x}}}}{{100}} = 1440 \times \frac{{125}}{{100}}$$ ⇒ $$\frac{{1440 \times 125}}{{75}}$$ = Rs. 2400This Question Belongs to Arithmetic Ability >> Profit And Loss
X×100/12100/75=1440
X=2400
it should be
1440/75*100=1920
1920/75*100=2560
marked price 2560
simply u fins S.P. (1440 X 125/100 = 1800)
THEN U KNOW THAT discount on M.P. = S.P.
SO THAT,,,,, M.P X 75/100 =1800
1800 X 100/75 =2400 ans
