I am still not agree on this. As in the question it is asking for the increament in share of remaining persons. 1/7 is the new share but not the increament.

Rate of car : 8x.
Each one contributed: x.
If one person withdraws, 7x will be left. To make it 8x again, each one gives x/7.
x+x/7. 1/7 increased.
Each one contributed: x.
If one person withdraws, 7x will be left. To make it 8x again, each one gives x/7.
x+x/7. 1/7 increased.

Simple one:
One's share is 1/8
Seven person's share is 7/8
Ans = (1/8)*(8/7)(simple one person's share divide by seven persons share)
= 1/7
One's share is 1/8
Seven person's share is 7/8
Ans = (1/8)*(8/7)(simple one person's share divide by seven persons share)
= 1/7

Let us take price of car R.s 80.
Can share 8 peple8/8 each R.s1.
One person withdraws so now.
can share 7 people 8/7,
1-8/7 = 1/7.
Can share 8 peple8/8 each R.s1.
One person withdraws so now.
can share 7 people 8/7,
1-8/7 = 1/7.

It is given that share would be divided among remaining person so why 1/8 is divided, it should be 1/7 can anyone clarify?

I think 1/8 is right answer
total increase is 1/56
this is divided among 7 equally
means every one's share is 1/8
total increase is 1/56
this is divided among 7 equally
means every one's share is 1/8

When 8 are sharing 1/8.
When seven are sharing 1/7.
Individual increment (1/7)-(1/8)=1/56.
So, the answer is 1/56.
When seven are sharing 1/7.
Individual increment (1/7)-(1/8)=1/56.
So, the answer is 1/56.

Assume total rent is 100.
100 ÷ 8 = 12.5.
Each share 12.5.
One person withdraws 8 - 1 = 7,
12.5 ÷ 7 = 1/7.
100 ÷ 8 = 12.5.
Each share 12.5.
One person withdraws 8 - 1 = 7,
12.5 ÷ 7 = 1/7.

The answer is 1/56. That is the increment that everyone's, remaining in the group, share will be increased by.

If car rate is x and initial contribution is why then,
Increased contribution of each person is x/56 or y/7.
Increased contribution of each person is x/56 or y/7.
