A person sold a TV for Rs. 9400 then he lost a particular amount. When he sold another TV of the same type at Rs. 10600, his gain was double the former loss. What was the cost price of each TV?

According to the question,
Given,
Loss = Cost price - 9400 = x ......(i)
Profit = 10600 - Cost price = 2x .......(ii)
Put the value of equation (i) in equation (ii)
∴ 10600 - Cost price = 2
(Cost price - 9400)
10600 - Cost price = 2 Cost Price - 18800
3 Cost price = 29400
$$\eqalign{ & {\text{Cost price}} = \frac{{29400}}{3} \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = 9800 \cr & {\text{Cost price}} = {\text{Rs}}{\text{. 9800}} \cr} $$
