Plz help me guys ╥﹏╥

Let the M.P of the article be x.A discount of 30% was given on the M.P.So the selling price of the article (S.P) = M.P - Discount.Discount = 30% of x

Now S.P. = M.P - Discountor, S.P.

The shopkeeper loses Rs 400.Loss = C.P - S.Por, C.P = Loss + S.P.or, C.P = Now if he allows 10% discount then the gain is Rs 200.Gain = S.P - C.Por, S.P = Gain + C.PS.P = Discount = 10 % of x S.P. = M.P - Discountor, The M.P of the article is Rs 3000.C.P = The cost price is Rs 2500.

Answers:

Rs. 3000, Rs. 2500

Hope you could understand.

If you have any query, feel free to ask.

9/12 is the answer because 3/4 times 3 each is 9/12

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
