What is the source of this question?
"One part of the number is the square of 6" - doesn't make any sense

Let the number be x.

Then, \(44^2 < x < 45^2\)

or, 1936 < x < 2025 ... (1)

Therefore, the number lies between 1936 and 2025.

It is also given that one part of the number is the square of 6. This means that one factor will be 36.

LCM of 36 and 5 = 180.

Therefore, the number will be a multiple of 180,

i.e., x = 180 x 11 = 1980.

This is the only value that satisfies the condition in equation (1).

This is a practice question. GMAT would use different language.

"one part of the number is square of 6" could also mean the number has 36 in it. in option 'b', product of 4 and 9 is 36, and its a multiple of 5. i feel answe is 'B'
