The marked price of one pen is '₹x'. The selling price of one packet of 'x' pens, after a discount of 15%, is ₹1,360. What is the value of 'x'?
Answer & explanation
Correct answer: option 2
Let the MRP of one packet of x pens is y.
According to the question,
y of (100-15)% = 1360
y of 85% = 1360
y = 1600
The marked price of one pen is '₹x'.
MRP of one packet of 'x' pens = marked price of one pen × number of pens in one packet
y = x × x
Put the value of y in the above equation.
1600 = x × x
x2 = 1600
x = 40
