watch
a. Rs 1550 b. Rs 2000
c. Rs 2325
d. Rs 2500​

Answer 1

Answer:

GIVEN

We are given that Rahul made a loss by selling a watch for Rs 1860 and made a loss of 20%

Selling Price(SP) = Rs 1860

Loss = 20%

TO FIND

We need to find the cost price of the watch (CP).

SOLUTION

Selling Price = Rs 1860

Loss % = 20%

%age Loss is given by:-

Loss(%) = (Cost price - Selling price) / (cost price)  * 100

==>  CP - SP / CP * 100

 

==> 20 = CP - 1860/ CP * 100

==> CP - 1860 = CP/5

==> 4CP/5 = 1860

==> 4CP = 1860 * 5

==> CP = Rs 2325

The answer to this question is (C) Rs.2325

Points To Remember:-

• When we jave to find gain percent ,  we can calculate by the formula, (SP>CP)

     %gain = (SP-CP)/(CP)*100

• When we have to find loss percent , we can calculate by the formula (CP>SP)

     %loss = (CP-SP)/(CP)*100
