If the product of three consecutive positive integers is 15600 then the sum of the squares of these integers is

A) 1777

B) 1785

C) 1875

D) 1877

Option (D)

From CAT 2017 – Quantitative Aptitude – Number Systems, we can see that,

a (a+1) (a+2) = 15600

The consecutive numbers will be 24, 25 and 26

We have to find,

a^2 + (a+1)^2 + (a+2)^2 = (24)^2 + (25)^2 + (26)^2 = 1877

Quantitative Aptitude – Number Systems – Q1: If a, b, c are three positive integers such that a and b are in the ratio 3 : 4 while b and c are in the ratio 2:1, then which one of the following is a possible value of (a + b + c)?

Quantitative Aptitude – Number Systems – Q2: The numbers 1, 2,â€¦,9 are arranged in a 3 X 3 square grid in such a way that each number occurs once and the entries along each column, each row, and each of the two diagonals add up to the same value.
