If (a × b)(c × d) = (e × f); (c × d)(e × f) = (a × b) and (e × f)(a × b) = (c × d) where a, b, c, d, e and f are nonzero integers, then the sum of all the possible values of (a + b + c + d + e + f) is
a 8
b 6
c 0
d 16

Let us assume that the earth becomes a cube. What is the ratio of the minimum distances that a person has to travel along the surface to get to a point diagonally opposite on the cuboidal earth to the distance that he would travel on the spherical one. (Assume that the length of a side of the new earth is the radius of the earlier one.)

Let n be a positive integer. Let k be the number which needs to be subtracted from n to get the nearest perfect square less than or equal to n and let l be the number which needs to be added to n to get the nearest perfect square more than or equal to n. If (n – kl) has p number of factors then which of the following is definitely true?
