Question

19 Navan sells two radio sets: one for 2,800 and the other for? 4,200. On one he gains
20% and on the other set he loses 10%. Find his gain or loss per cent in the whole
transaction.​

Answer 1

There is neither profit nor loss

Step by step explanation:-
1st radio:
SP = 2800
Gain = 20%
CP = SP * 100/ 100 + profit
That is: 280000/ 120 = 2333.33
Round it of: 2333

2nd Radio:
SP = 4200
Loss = 10%
CP = SP * 100/ 100- loss
that is: 4200*100/ 100 - 10 = 4666.66
Round of: 4667


Total CP = 2333 + 4667 = 7000
Total SP = 2800 + 4200 = 7000

Since CP and SP are same there is neither profit and loss
