Which statement correctly explains the difference between a right cylinder and an elliptic cylinder? A right cylinder has triangular bases while an elliptic cylinder has oval bases.
A right cylinder has circular bases while an elliptic cylinder has oval bases.
A right cylinder has rectangular bases while an elliptic cylinder has oval bases.
A right cylinder has rectangular bases while an elliptic cylinder has circular bases.

1. If it is intersection then it SHOULD be included in both the sets right? Now we know that odd numbers from 1-100 but the second set are multiples of 5 from 50-150! So we mainly need to look for common numbers which are ODD and are a MULTIPLE OF 5 BETWEEN 50 - 100!! So A={51,53,57,59,6199} B={55,60,65,7095} [We stop till 100 because set A has no such element] So what is A ∩ B here? A ∩ B = {All odd numbers and multiples of 5 between 50 - 100}
