Question

A man bought 2 watches for Rs. 400. He sold one at a profit of 10% and the other at a loss of 10% and then he found that each was sold for the same price. Find the cost price at each.​

Answer 1

Answer:

180 and 220

Step-by-step explanation:

let cost of watches are X and y

so

x+y=400---------1

according to question

(x-x*10/100) =(y+y*10/100)

90X=110y-------2

from 1

x=400-y

90(400-y)=110y

36000-90y=110y

36000=200y

y=360/2=180

and

x=220
