Answer:
430
Step-by-step explanation:
<u>Given :-</u>
- By selling a watch on 400 and 460’. Loss and profit happened respectively.
- The loss and profit are equal.
And we need to find out the CP .So ,
<u>Let :- </u>
- CP be x
- Profit and Lost be y .
<u>According to the Question :- </u>
460 = x + y <em>( Profit)</em>
400 = x - y <em>( Loss)</em>
<u>Adding both :- </u>
460 + 400 = x + y + x - y
860 = 2x
x = 860/2
x = 430
<u>Hence the Cost price of the watch is 430 .</u>
