Question
Four number-pairs are given, out of which three are
alike in certain manner and one is different. Choose the different number-pair.Solution
The second number is divisible by the first: (64 ÷ 8) = 8 (84 ÷ 12) = 7 (128 ÷ 16) = 8 (165 ÷ 20) leaves a remainder of 5. Option (d) does not fit the pattern
- The sum of HCF and LCM of two numbers is 425. If the LCM is 16 times the HCF, and one number is 25, find the second.
If the product of two numbers is 108 and their HCF is 6, then find the LCM of the given two numbers.
The LCM of two numbers is 5 times of their HCF. The sum of LCM and HCF is 300. If one of the number is 250, then the other number is:
