Marks: +1, -0

A man sold his watch at a loss of 5%. Had he sold it for ₹ 56.25 more, he would have gained 10%. What is the cost price of the watch (in ₹) ?

Solution:

Let Cost Price of watch be ₹ x
S.P

=x-5/100x=95x

If S.P

= 0.95x + 56.25

then profit = 10%

{0.95x+56.25-x}/x×100=10

56.25/x-0.05=1/10

56.25/x=1/10+5/100=3/20

x=56.25×20/3=375
