The cost price of 16 notebooks is equal to the selling price of 12 notebooks. Find the gain percent

❀ʀᴇǫᴜɪʀᴇᴅ ᴀɴsᴡᴇʀ:

33% GAIN / PROFIT on COST BASIS ( applies for the 12 notebooks sold. Don't know at what price, the rest of 4 notebooks would be sold).

Assume the total cost of 16 notebooks as Monetary unit 100, which we would label as M. (Unit not specified in question). Thus 100 M.

Hence the cost of 22 notebooks =(12/16)×100=75 M

Now the selling price of these 12 notebooks is same as cost of 16, which is 100M.

Gain = 100M-75M=25 M.

Profit % = 25M/75M=33%.
