Direction: Each of these questions is followed by two statements, I and II. Mark the answer as
1. if the question can be answered with the help of statement I alone. 2. if the question can be answered with the help of statement II alone. 3. if both statement I and statement II are needed to answer the question. 4. if the question cannot be answered even with the help of both the statements.
What is the number x?
I. The LCM of x and 18 is 36. II. The HCF of x and 18 is 2.
Explanation:
We know that product of two numbers = LCM × HCF = 36 × 2 = 72. So x = 7218 = 4.
Hence, both the statements are required to answer the question.
