​

Answer 1

Answer:

Let the M.P. of the article = Rs.100

Discount = 10%

∴ S.P. = 90% of Rs.100 = Rs.90, Profit = 20%

∴C.P.=Rs.

120

90×100

=Rs.75

If the discount is 20% then S.P. = 80% of Rs.100 = Rs.80

∴ Required profit % =

75

(80×75)

=100 =

The lowest selling price

Solution,

To solve this following problem we have apply some mathematical principles,

Let,the M.P of the article = Rs 100.

Discount = 10%

∴S.P= 90%of Rs.100

⇒Rs 90

⇒Profit =20% of M.P

⇒20

∴C.P = M.P+Profit

⇒100+20

⇒120

∵Required S.P= C.P+Profit

⇒120+90

⇒Rs. 210

Now,If the discount is 20% then S.P =80% of M.P

⇒80% of 100

⇒80

∴C.P = M.P+Profit

⇒100+80

⇒180

∵Required S.P= C.P+Profit

⇒180+80

⇒Rs.260

Note: The above question is wrong but with the help of this procedure we will be able to find the other problems.
