Shortcut:
profit or loss percentage =
Net gain or loss
/
Cost Price
x 100
Here, C.P = 1200 + 200 = 1400 (Expenditure is added in C.P), S.P = 1680, If S.P > C.P, then the deal is in gain.
Net Gain = S.P − C.P = 1680 − 1400 = Rs 280

Using these value in shortcut, we get:
Gain % =
280
/
1400
x 100 = 20
Hence, there is 20% gain in the deal.
