Question

2. There was a 12-1upon2% increase in the number
of new admissions to a school in 2012 compared
to the year 2011. If the number of new
admissions in 2011 was 112, find the number of
new admissions in 2012.​

Answer 1

Answer:

Old ratio (A, B and C) = 3 : 2 : 1

W is admitted for 1/6th share

A's contribution in favour of W = 3/30 (note 1)

B's contribution in favour of W = 2/30 (note 1)

New ratio = Old ratio - Sacrificing ratio

A's new share = (3/6) - (3/30) = 12/30

B's new share = (2/6) - (2/30) = 8/30

C's share = 1/6 or 5/30 (it remains unchanged)

W's share = 1/6 or 5/30

Therefore, new profit sharing ratio of A, B C and W is 12 : 8 : 5 : 5

Notes:

1. In silent question, A and B will contribute in favour of in old ratio.
