Tarun invited 750 persons to a party. Every person that came
to the party, came by a car such that exactly six persons
came in each of the three different cars and exactly seven
persons came in each of the remaining cars. At the party,
when every person including Tarun was seated in a group of
eleven, one group fell short by four persons. If maximum
possible number of persons came to the party, then out of
the persons who were invited by Tarun, how many persons did
not come to the party?

i think it is 11.
751/11 = 68groups and 3members(including Tarun)
max number attended = 748 - 4(short in one group)
= 744
now 4+2(excluding Tarun)= 6 short
now they all came in car
6 * 3 + 7 * xcars = 744
7 * xcars = 726
the value should be 7 divisible because all came in car,
there is 5 more in 726,
i.e 726/7 remainder 5
so already we have 6 members short and now 5 more
6 + 5 = 11
