- Distribute 10 toffees to each of 5 persons. so total 50 toffees , now remaining toffees are 6 which we hav to distribute among 5 person so this can be possible in
6+5-1C5-1=10C4=10C6 so option will be A
Distribute 10 toffees to each of 5 persons. so total 50 toffees , now remaining toffees are 6 which we hav to distribute among 5 person so this can be possible in
(6+5-1)C(5-1)=10C4=10C6 so option will be A - 10 years agoHelpfull: Yes(29) No(7)
- formula is : m+r-1 C r-1
Here m=6 after distributing 10 toffees to each child and r=5(no. of child)so ans is 6+5-1C5-1=10C4=10C6 - 10 years agoHelpfull: Yes(13) No(1)
- at first 50 tofees will be distributed among 5 persons (10+10+10+10+10) that is it happens only in 1 way.and now remaining 6 toffes will be distributed among 5 person in 6p5 ways. so the answer will be 1*6p5=6p5 ways.

- firstly we distribute to each one,10 toffees...so we are left with 6 toffees.Now we have to distribute them among 5.....so
first toffee can be given in 5 ways
2nd can also be given in 5 ways...and so on
to 5*5*5*5*5*5=5^6 ways (Ans) - 10 years agoHelpfull: Yes(4) No(1)
- 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(4) No(0)
- 56 toffees 2 be divided among 5 persons den each person can get 10 toffees...remaining 6 toffeess 2 be distributed among 5 diffirent persons can be done in 6+5-1C5-1 ways=9c4ways..=126

- no of ways to give 6 toffes to one person =5
no of ways to give to give 5 toffes to one person and one toffee to other 10
no of ways to give to give 4 toffes to 2 person and one toffee to other 10
no of ways to give to give 3 toffes 5
total no of ways=5+10+10+5=30 - 10 years agoHelpfull: Yes(0) No(2)
