"C.P. of 120 kg of mixture = Rs. (80 x 13.50 + 120 x 16)
= Rs. 3000. S.P. = 116% of Rs. 3000
= Rs. ([116/100]×3000)= Rs. 3480
∴ Rate of S.P. of the mixture = Rs. (3400/200) per kg = Rs. 17.40 per kg.

C.P. = Rs. (]100/119.6]×17940) = Rs. 15000
Now C.P. = Rs. 15000, S.P. = Rs. 19500.

Then , S.P. = Rs. (90100×100)(90100×100) = Rs. 90, gain = 20%
∴ C.P. = Rs. ([100/120]×90)= Rs. 75
New commission = Rs. 20; New S.P. = Rs. 80
∴ New profit = ([5/75]×100)% = 20/3% . ."
