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

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

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.

Let take the arrangement cost is 64 rupees.
originally 8 person share is as each 8 rupees.
Due to one person withdraw the amount is divided as 64/7=9.1
i.e each one amount is increased by 1.1 instead of 8.
So from the question how it is calculated explain any one please?

See according to the question the answer will be 1/56 in my logic.
now explain it-
Let the cost of car be 1 since we dont know the price of car.
Now it is divided equally among 8 people so each person's share=1/8
Then it is divided equally among 7 people so each's person share=1/7
So, increase in share of each person should be 1/7-1/8=1/56.

Then it is divided equally among 7 people so each's person share=1/7
So, increase in share of each person should be 1/7-1/8=1/56.

Example if Rs.30 is shared by six persons one's share = Rs.5 (1/6) if one person is withdraw from it then one person's share.
= Rs.6 (1/5).
Here there are 5 persons each one's share is increased by one rupee so the share of each one increased by 1/5 likewise here finally 7 persons each one share is increased by 1/7.
= Rs.6 (1/5).
