Question

By selling 12 oranges for a rupee, a man loses 20%. How many for a rupee should he sell to gain 20% ?

Answer 1

For 1 orange:

1/12 rupees is the cost.
The loss is 20%.
So 1/12 rupees is 80% of the cost price of 1 orange.

So 1/12 = CP * 80/100

Find CP, then you need to find the cost of one orange with gain 20%. For that, multiply the CP by 120/100.
