Question

When a pen is sold at a discount of 15%, there is gain of Rs 10, but if it is sold with a 25% discount, there is a loss of Rs 2. What is the marked price of the pen? (Please answer Fast!!)

Answer 1

Answer:

A gain of 2r at 15% discount becomes a loss of 10r with 25%.

thus a movement of 12r represents 10% and 100% is 120r

proof 120r less 15% = 102 less gain 2r= cost 100

120r less 25% = 90r less cost 100r= 10r

simples

Answer 2

Step-by-step explanation:

here,

case l

Let, the market price (m.p) = x

discount precent = 15%

profit =Rs 10

case ll

sp. = ?

discount precent = 25%

loss = ?

we know,

sp = mp(1-dis%)

= x ( 1 - 15/100)

= x(100-15)/100

= 0.85x

again,

profit amount = sp-cp

or, 10 = 0.85x - cp

cp = 0.85x- 10

case ii

sp = mp(1-dis%)

= x( 1 - 25/100)

= 0.75x

Again,

loss = cp - sp

2 = (O. 85x - 10) - O. 75x

or, 2 + 10 = O. 85x - O. 75x

or, 12 = O. 10x

or, 12/0.10=x

so, x = Rs. 120

thus, the market prices (mp) = Rs. 120
