My Solution ::
at least 70% of people like apples, at least 75% like bananas so at least 45 % will like both, call it X. Now take the third fruit 80% like cherries.
Now we have to find percentage of people who will like at least of x and cherries, it will be 25 %
so the answer is 25%
You have to divide your answer by 3 because it is talking about some equivalent, so the answer should be 81/3 i.e 27.

In case of favorable no. of cases we have
x1 + x2 + x3 = odd in only two cases.
all three are odd.
two are even and one is odd.
Therefore, we have
1. 2 even, 1 odd ----> 5c1*5c2
2. 3 odd --->>> 5c3
total no. of cases = 10c3
Hence prob. = (5c1*5c2 + 5c3) /10c3 = 1/2
so my answer is d
I think, 1024 which is < 1080 will have maximum length.
1024 = 2.2.2....10times..
so the maxium length would be 10.
so my answer is B
