- 1 fruit can be selected in 6 ways
2 fruits can be selected in 6c2 ways
3 frts cn b selected in 6c3
4 fruits cn b selected 6c4
5 friuts cn b selectd in 6c5
and all 6 friut in 1 ways;
since here it asking how many we can select different no of fruits ...total fruits is avaible is 3o;but this is the minimum case of different selection of fruits ...no of ways sud be greater than 6+15+20+15+6+1=63;for seven fruits more than 66 would be there...so answer is none of the above

- each variety can be selected in 6 ways i.e, 0 or 1 0r 2 0r 3 0r 4 0r 5
so from all the fruits we can select in 6*6=36 ways
but this includes selection of no fruit...
ans=36-1=35 ways

- Lets consider the case of the first fruit. There are 5 fruits of the variety. We have to select either 0/1/2/3/4/5 of this varity of fruit. this can be done in 6 ways.
Same is the case with each variety of fruit, it can be done in 6 ways.
So, total 6 power 6. But we have to exclude the case of selection o fruits of each variety. This particular case must be excluded.
So, total of (6^6)-1 ways. Choice (c) - 11 years agoHelpfull: Yes(0) No(0)
