Question

5.) A shopkeeper sold a phone at a loss of 7%. Had he sold it for
Rs. 28 more, he would have gained 21%. Find the cost price
of phone.​

Answer 1

Answer:

rs 100

Step-by-step explanation:

let price = x

so selling price at 7% loss = .93x

and sp at 21% profit = 1.21x

so rs 28 more at 21% i.e.

.93x + 28 = 1.21x

1.21x - .93x = 28

x = 28/.28 = 28/28*100

x = rs 100 Answer
