Question

17. If a pen cost Rs.50 after 10% discount, then what is the actual price or marked price of the
pen?​

Answer 1

Answer:

₹45.45

Step-by-step explanation:

SP = 50

d = 10 %

MP = ? (suppose x)

$SP=MP + \frac{d \times MP}{100} \\ 50=x+\frac{10x}{100} \\ 50=x+0.1x\\1.1x=50\\x=\frac{50}{1.1} =\frac{500}{11} =45.45$

Thus, the price of pen is ₹ 45.45
