Select the set in which the numbers are related in the same way as are the numbers of the following set.
5, 30, 40

5, 30, 40 ==> Second number = $$5\times(5+1)$$ = 30. third number = $$5\times(5+3)$$ = 40

Option (a) 4, 25, 32

Second number = $$4\times(4+1)$$ = 20. third number = $$4\times(4+3)$$ = 28

Here the second and third numbers are not as per the given logic. So this will not be the correct answer.

Option (b) 6, 42, 49

Second number = $$6\times(6+1)$$ = 42. third number = $$6\times(6+3)$$ = 54

Here the third numbers is not as per the given logic. So this will not be the correct answer.

Option (c) 8, 72, 88

Second number = $$8\times(8+1)$$ = 72. third number = $$8\times(8+3)$$ = 88

This will be the correct answer. Because here the given logic is applicable.

Option (d) 7, 56, 77

Second number = $$7\times(7+1)$$ = 56. third number = $$7\times(7+3)$$ = 70

Here the third numbers is not as per the given logic. So this will not be the correct answer.
