We have two unknown positive integers m and n, whose product is less than 100.
There are two additional statements of facts available:
mn is divisible by six consecutive integers { j, j + 1,...,j + 5 }
m + n is a perfect square.
Q. Which of the two statements above, alone or in combination shall be sufficient to determine the numbers m and n?
  • a)
    Each statement alone is sufficient to answer the question.
  • b)
    Both statements taken together are sufficient to answer the question, but neither statement alone is sufficient.
  • c)
    Statement 2 alone is sufficient, but statement 1 alone is not sufficient to answer the question.
  • d)
    Statements 1 and 2 together are not sufficient, and additional data is needed to answer the question.
  • e)
    Statement 1 alone is sufficient, but statement 2 alone is not sufficient to answer the question.
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
We have two unknown positive integers m and n, whose product is less ...
Given, m and n are two positive integers having product less than 100
Statement 1:
mn is divisible by 6 consecutive integers. This means mn must be divisible by the LCM of these 6 integers multiples.
Only numbers from 1 to 6 satisfy this with LCM 60. Any other set of 6 consecutive integers clearly exceeds 100 as its LCM.
Only such a number satisfying the condition is 60.
60 can further be expressed as the product of two positive integers in the following ways:
1 x 60, 2 x 30, 3 x 20, 4 x 15, 5 x 12 and 6 x 10.
So, no unique values of m and n can be determined from the above.
Statement 2:
m + n is a perfect square.
From this statement alone too no unique set of solutions can be determined.
From Statements 1 and 2: Only the pair 6 x 10 satisfies the condition.
Hence, both statements taken together are sufficient to answer the question, but neither statement alone is sufficient.

We have two unknown positive integers m and n, whose product is less ...
Given:
We have two unknown positive integers m and n, whose product is less than 100.
mn is divisible by six consecutive integers { j, j+1,...,j+5 }
m*n is a perfect square.

To find:
Which of the two statements above, alone or in combination, is sufficient to determine the numbers m and n?

Solution:
Let's analyze each statement separately and then combine them to see if we can determine the values of m and n.

Statement 1: mn is divisible by six consecutive integers { j, j+1,...,j+5 }
This statement implies that mn is divisible by 6! (factorial of 6) because it is divisible by six consecutive integers. In other words, mn is divisible by 6*5*4*3*2*1 = 720.

There are two possibilities for mn:
1. mn = 720k, where k is a positive integer.
2. mn = 720k', where k' is a positive fraction less than 1.

Now, let's consider the values of m and n separately:

Case 1:
If mn = 720k, then both m and n can be factors of 720k. Since the product of m and n is less than 100, we need to find two factors of 720k whose product is less than 100.

The prime factorization of 720 is: 2^4 * 3^2 * 5.
Possible pairs of factors of 720 are:
- (1, 720)
- (2, 360)
- (3, 240)
- (4, 180)
- (5, 144)
- (6, 120)
- (8, 90)
- (9, 80)
- (10, 72)
- (12, 60)
- (15, 48)
- (16, 45)
- (18, 40)
- (20, 36)
- (24, 30)

Out of these pairs, we need to find a pair whose product is a perfect square. Since we don't have any information about the values of m and n, we cannot determine which pair satisfies this condition. Therefore, statement 1 alone is not sufficient to determine the values of m and n.

Case 2:
If mn = 720k', where k' is a positive fraction less than 1, then both m and n are fractions. Since the question specifies that m and n are positive integers, this case is not possible. Therefore, we can ignore this case.

Statement 2: m*n is a perfect square
This statement implies that the product of m and n is a perfect square. Let's analyze this statement further.

If m*n is a perfect square, then both m and n must be perfect squares themselves. We can represent m and n as m = p^2 and n = q^2, where p and q are positive integers.

Now, we can rewrite the product mn as mn = p^2 * q^2 = (pq)^2, which is a perfect square.

Since both m and n are perfect squares, we can find their values by finding the square roots of mn. Therefore, statement 2 alone is
