Bull's work rate = 1 field / 5 days = 1 / 5 field/day

Buffalo's work rate =1 field / 10 days = 1 / 10 field/day

3 Bulls = 3 × 1 / 5 = 3 / 5 field/day

2 Buffaloes = 2 × 1 / 10 = 2 / 10 = 1 / 5 field/day

Total work rate = (3 / 5) + (1 / 5) = 4 / 5 field/day

Time = Total Work / Work Rate =  1field / (4/5 field/day) = 5 / 4 days = 1.25 days

Thus, the correct answer is 1.25 days.
