My teacher had 3 big boxes of sweets. One box contained red sweets, one green and one yellow. Each learner was given 5 sweets of two different
colours. Every learner in the class received a different combination of colours. What was the maximum number of learners that could have been
in the class?
Is it the answer is 120 ?

3 - All of same colour
6 - 4 Of same colour
9 - 3 Of same colour
3 - 2 of them of same colour (After Eliminating the repitition)
Altogether maximum of 21 Learners possible.
There are 7 Membrs in the class.
They got 7 different combinations of sweets
the possible combinations are
1.all 5 red 2.all 5 green 3.all 5 yellow
4.red + green 5.green + yellow 6.red +yellow
7.red + green + yellow
James, I gues it is time you decide which side the answers belong to. Atleast you can turn down the answers which are incorrect.

"Each learner was given 5 sweets of two different colours"
-- So all your answers are wrong
Suresh's Answer is correct.
The right answer is 12.
Suresh, Please leave ur solution
In five you have only two combinations are there ...ie (1+4) (2+3)
Three boxes are there...the combination are coming like this...
(1,0,4) (1,4,0) (0,1,4) (0,4,1) (4,1,0) (4,0,1)
(2,0,3) (2,3,0) (0,2,3) (0,3,2) (3,2,0) (3,0,2)
Totally 12 combinations will come... so maximum 12 learners are there in that class.
