Question
Two gadgets, ‘P’ and ‘Q’, were sold for Rs. 2800
each. The gain on gadget ‘P’ is equal to the loss on gadget ‘Q’. If the cost price of gadget ‘P’ is Rs. 1400 less than that of gadget ‘Q’, find the cost price of gadget ‘P’.Solution
Let the cost price of gadget ‘P’ be Rs. x
Therefore, cost price of gadget ‘Q’ = Rs. (x + 1400)
According to the question,
2800 – x = x + 1400 – 2800
Or, 2x = 2800
Or, x = 1400
Therefore, cost price of gadget ‘P’ = Rs. 1400
