Question

A dealer allows a discount of 10% and still gains by 10% what should be the marked price if the cost price is 900 rupees

Answer 1

Answer:

1100 rupees

Step-by-step explanation:

let marked price be x.

c.p=900

so 10%of x =x/10

s.p=m.p-discount

= x - x/10

= 9x/10

now, gain is equal to s.p- c.p

10% of c.p=s.p-c.p

= 9000/100=9x/10 - 900

90+900=9x/10

x=1100.
