A and B are partners in a firm sharing profits in the ratio of 3:2. They admitted M as a new partner for 1/4 share. The new profit sharing ratio between A and B will be 2:1. Calculate their sacrificing ratio.

Solution

✅ Correct Option: 1

Given Information:

  • Old ratio of A and B = 3:2
  • M is admitted for 1/4 share
  • New ratio between A and B = 2:1

Finding Old Shares:

A's old share = 35\frac{3}{5}

B's old share = 25\frac{2}{5}


Finding New Shares:

M's share = 14\frac{1}{4}

Remaining share for A and B = 1−14=341 - \frac{1}{4} = \frac{3}{4}

This 34\frac{3}{4} is divided between A and B in the ratio 2:1

A's new share = 34×23=12\frac{3}{4} \times \frac{2}{3} = \frac{1}{2}

B's new share = 34×13=14\frac{3}{4} \times \frac{1}{3} = \frac{1}{4}


Calculating Sacrifice:

Sacrifice = Old Share - New Share

A's sacrifice = 35−12=6−510=110\frac{3}{5} - \frac{1}{2} = \frac{6-5}{10} = \frac{1}{10}

B's sacrifice = 25−14=8−520=320\frac{2}{5} - \frac{1}{4} = \frac{8-5}{20} = \frac{3}{20}


Sacrificing Ratio:

A's sacrifice : B's sacrifice = 110:320\frac{1}{10} : \frac{3}{20}

Converting to same denominator: 220:320\frac{2}{20} : \frac{3}{20}

Sacrificing Ratio = 2:3

The correct answer is Option 1: 2:3
