These questions are based on the information given below: Two siblings - Bunty and Babli - divide 10 fruits equally between them. The fruits are divided such that, each of them has at least one banana and at least one apple. Also, the number of appeals and the number of bananas with Bunty is different from the number of appeals and the number of bananas with Babli. When asked about the details of the fruits with each of them, they came up with the following replies. Bunty:I have more than two bananas. Babli has less than two appeals Babli:Bunty has more than two apples. I have less than two bananas. It is known that, of the statements made by each of them, exactly one is true and the other is false, in any order. If the number of apples with Babli is less than the number of apples with Bunty, then how many bananas are there with both of them together?
