Explanation:

C.P of 12 balloons = 10
C.P of 1 balloon = 10/12 = 5/6
S.P of 10 balloons = 12
S.P of 1 balloon = 12/10 = 6/5
Profit = S.P - C.P
= 6/5 - 5/6
= (36 - 25)/30
= 11/30
Profit % = ( Profit/C.P ) × 100
= {(11/30)/(5/6)} × 100
= (11/30) × (6/5) × 100
= 44%

Hence, option 3 is the correct answer.
