Solution:

Let the CP of 1 soap = S
Thus, the CP of 1 toothbrush = 0.6S
Given that, SP of 1 soap = 1.15 S and SP of 1 toothbrush = 0.6S+20
Also,

15×1.15×S+8×(0.6S+20)-15S-8×0.6×S=385

Thus, solving we get S = 100
Hence, Total CP of 20 soaps and 12 toothbrush

=20×100+12×60=2720

SP of 15 soaps and 8 toothbrush

=15×1.15×100+8×80=2365

Thus, the overall loss

=2365-2720=355

Rs.
Hence, option A is the correct answer.
