Ans is B
profit=96 *20/100 = approx 19 rs.
so cost price= 96(selling price)-19 =approx 77 rs

Now apply hit and trial.
if 3:2 then total 5 parts are there (3 of ghee + 2 of oil).
3 parts of ghee means 60% of total solution while 2 parts of oil means 40% of total solution.

so cost price will be as: 100*60/100 + 50 *40/100 = 80 ~=77

answer is B
we can do it by alligation

SP of mixture is 96 making profit 20%
therefor CP is 80

Now using alligation

100 50

80

(80-50)=30 (100-80)=20

so the ratio is= 30/20
3:2

Deepu  (4 years ago)

using mixture and alligation:
96*100/120=80/kg
100 50
80
here 100-80=20 and 80-50=30...we will get 20 and 30 in cross multiplication so by solving further we get
=30 =20=================30:20=3:2 Answer
