cost of 3 gms of coffee by putting in 2 parts of a 33p. a gm. grade to 1 part of a 24p. a gm = 90 paisa
cost of 1 gms of coffee by putting in 2 parts of a 33p. a gm. grade to 1 part of a 24p. a gm = 30 paisa

cost of 3 gms of mixture changed to 1 part of the 33p. a gm. to 2 parts of the less expensive grade = 81 paisa
cost of 1 gms of mixture changed to 1 part of the 33p. a gm. to 2 parts of the less expensive grade = 27 paisa

Diff in cost for 1 gm mixture = 3 paisa
diff in cost for 100 gm mixture = 300 paisa = 3 Rs.
