Answer 2

Let Cost Price be Rs.100
Loss = 5% of Rs.100
= 5/100 × Rs.100
= Rs.5

& Selling Price = Rs.100 - Rs.5 = Rs.95 (Since, Selling Price = Cost Price - Loss)

When Selling Price = Rs.95, Cost Price = Rs.100

When Selling Price = Re.1, Cost Price = Rs.100/95

& When Selling Price = Rs.540, Cost Price = Rs.100/95 × 540

Therefore, the Cost Price = Rs.568.4210526 Ans.

Ans.) It's Cost Price is Rs.568.42.
