- first we will distribute 10 toffees to each of 5 persons i.e total 50 toffees ,
now remaining toffees are 6 which we have to distribute among 5 person so this can be possible in
m+r-1 C r-1
=>6+5-1C5-1=10C4 - 10 years agoHelpfull: Yes(6) No(1)
- ans 10 C 6

- shudnt it be 10C5...why r u taking n+r-1Cr-1.. why not n+r-1Cr

- all of u below are wrong.....sorry to say so....
its like..a+10 +b+10........e+10 =56
a+B....+E = 56-50 = 6
ans will be...................................(N-1)C (R-1)
6-1C 5-1 = 15ways ......esle wise also rohit use ur logics how can it be 210 ways to distribute if everyone already has 10....bestofluck - 9 years agoHelpfull: Yes(0) No(0)
