Answer:16%

________________________________

Step-by-step explanation:

20 dozen notebook bought in = 156 rs.

price of 1 dozen = 7.80 rs.

price after 10% gain = 7.80 + 10% of 7.80

= 7.80 + 0.78

= 8.58 rs.

price after 20% gain = 7.80 + 20% of 7.80

= 7.80 + 1.56

= 9.36 rs.

so total sale = 8*8.58 + 12 * 9.36

= 68.64 + 112.32

= 180.96 rs.

as we know that

%profit =180.96-156/156*100

=16

profit = 16%
