Q. The LCM of two numbers is 30 and their HCF is 5. One of the numbers is 10. The other is:
Answer: 15
Notes: Because, First number $latex \times$ Second number = LCM $latex \times$ HCF Let the Second Number be x. ∴ 10x = 30 $latex \times$ 5 $latex =>x=\frac{30\times 5}{10}=15&s=1$ Hence option [B] is the right answer.
