Question

What price a wholesaler mark a computer which cost him rs.15800to gain 15%after allowing a discount 21%.

Answer 1

Solutions :-


We have,

Cost Price = Rs 15800
Profit = 15 %
Discount on its marked price = 21 %


Selling price = C.P + Profit% of C.P
= Rs 15800 + 15% × 15800
= Rs 15800 + 2370
= Rs 18170


Now,

Marked price = (S.P × 100)/(100 - discount)
= Rs (18170 × 100)/(100 - 21)
= Rs 1817000/79
= Rs 23000



Answer : Marked price of computer is Rs 23000

Answer 2

Solutions :-

Given :

Cost Price = Rs 15800

Profit % = 15 %

Discount on its marked price = 21%

Find the Selling price of computer :-

S.P = C.P + Profit % of C.P

= 15800 + 15% of 15800

= 15800 + 0.15 × 15800

= 15800 + 2370

= 18170

Now,

Find the marked price of computer :-

M.P = (S.P × 100)/(100 - discount)

= (18170×100)/(100 - 21)

= 1817000/79

= 23000

Hence,

The marked price of computer is Rs 23000
