The cost price of the watch (in rs) is Rs. 375.

Step-by-step explanation:

Required Formulas:

S.P. = C.P. * \frac{[100 +- P or L]}{100}

Let the C.P. of the watch be Rs. "x".

Loss % = 5 %

So, the S.P. of the watch will be = \frac{100 - 5}{100} * x = \frac{95 x}{100} = 0.95 x

Now, it is given that if the man sells the watch for Rs. 56.25 more than the previous S.P. i.e., "0.95x" then he would have a profit of 10%, therefore we can write the eq. as,

0.95x + 56.25 = \frac{100+10}{100} * x

⇒ 0.95x + 56.25 = \frac{110x}{100}

⇒ 0.95x + 56.25 = 1.1x

⇒ 1.1x - 0.95x = 56.25

⇒ 0.15x = 56.25

⇒ x = \frac{56.25}{0.15}

⇒ x = Rs. 375
