You'll give 100 'units' to 6 of them, and 75 to 6, thus:
6 * 100 + 6 * 75 ==> 1050 units
Each 'unit' is valued at:
3000 / 1050 ==> 2.8571
Thus, you give:
6 * 285.71 + 6 * 214.28 ==> 2999.94, and you may keep the change ;-)

Subject: [PHP] help me to solve this math maze
i am making a program to give money to a group of people
lets say that i have to distribute 3000 among 12
people 6 of them are adult and will get 100%
6 them are children those will get 75% from the overall amount.
a common solution might appear as
divide 3000 to 12 which is 250
give 250 to adults and 75% percent of it to children which is 187.5
after this kind of calculation i have 375 more to give which was supposed to
be
equally distributed among them
can anyone understand my problem and assists me.
