A, B and C are partners sharing profits in the ratio of 1/2 : 1/4 : 1/4. New ratio on the retirement of B will be :

2:4 1:2 2:1 3:2

2:1

The correct answer is option 3- 2:1. Old ratio = 1/2 :1/4: 1/4 means 2:1:1 B retires and new ratio or gaining ratio is not given so old ratio becomes new ratio. So, new ratio will be 2:1.
