Mr. shah has to divide his assets worth rs 30 crores in 3 parts to be given to three of his sons ajay, vijay and arun ensuring that every son gets assets atleast 5 crores. in how many ways can this be done if it is given that the three sons should get their shares in multiple of 1 crore?
Read Solution (Total 14)
-
- Firstly we give 5 crores to each of the three sons
and hence it will cover 15 crores out of 30 crores.
Now rem 15 crores can be distributed among 3 sons using the formula...
(n+r-1)C(r-1) bcoz n ie 15 crores is identical here..
here we have n=15 &r=3
so 17c2=(17!)/(15!*2!)
thus we have 136 ways. - 11 years agoHelpfull: Yes(26) No(1)
- Firstly give, 5 5 5 crore to each one.
Now the remaining amount is 15 crore.
Now, Let amount given to ajay, vijay and arun is a,b,c respectively,
ie. a+b+c=15
and it requires two partitions.
therefore, (17!)/((15!*2!)
hence 136 ways of distributing the amount.

- ncr means no. of combinations of n things taken r at a time.
(n+r-1)c(r-1) thing means No. of ways of distributing n identical things among r persons when each persons may get any no. of things.
Since here in remaining 15 crore rupees any amount of money can be distributed to any three children so,,, the value will be..
(15+3-1)c(3-1)=17c2=(17*16)/2=136 - 11 years agoHelpfull: Yes(9) No(1)
- at 1st 5crores each so 15 crores divided among 3 of them.
then rest of the 15 crores will be distributed n-1cr-1 14c12=91 ways. - 11 years agoHelpfull: Yes(6) No(5)
- 78.
Let each one of the sons get 5 crore.
Now,the left 15 crore to be distributed among 3 sons will be
n-r+1Cr-1=15-3+1C3-1=13C2=78

- first divide each 5 crores
remaining can be done by (n+r-1)c(r-1)=17c2=136 ways - 11 years agoHelpfull: Yes(2) No(2)
- firstly divide 15 crore among 3 as 5 crore each.
now 15 crore is to be divided among 3 people such that each receives in a multiple of 1 crore.
so it will be n-1Cr-1.

- since each son gets 5 5 5 crore
rest 15 crore divided into three sons in 15c2=455
am i rght or wrong?? - 11 years agoHelpfull: Yes(1) No(7)
- 30-15crores=15crores. it divide in 3 person so v use 15c3=455 ans
