Question

a man gained rs 3000 by selling a watch allowing 10%discount on the marked price if he allows a discount of 40% on the marked price the loss would be rs3000 find the marked price of the watch

Answer 1

Let the C.P of goods = Rs. 100

S.P. of goods = 120% of 100 = 120

M.P. of goods = 120×10090=4003120×10090=4003

Difference of M.P and C.P = 4003−1004003−100

Difference % = 1003100×100=10031003100×100=1003

Answer 2

Step-by-step explanation:

case i

the profit (gained) price = Rs 3000

let the market price = x

discount precent = 10%

case ii

loss = Rs3000

discount precent = 40%

by case I

by using formula

sp1 = mp(1 -dis%)

= x(1 - 10 /100)

=x (100-10)/100

:: so sp1 =0.9x

Again,

profit amount = sp1 - cp

3000= 0.9x - cp

or, cp = 0.9x - 3000

case ii

sp2 = mp(1 -dis%)

= x(1 - 40 /100)

=x (100-40)/100

= 0.6x

Again,

loss = cp - s. p2

3000= 0.9x - 3000 - 0.6x

or, 3000 + 3000 =0.9x - 0.6x

or, 6000 = 0.3x

or, 6000/0.3 = x

:: x = Rs 20,000

so,the market price of watch is Rs20,000
