Let L be the LCM and Hbe the HCF of two given numbers. L and H are in the ratio 3 : 2. If the sum of the two numbers is 45, then what is the product of the numbers?

Two numbers are in the ratio 21 : 10. If their HCF is 11, then the sum of the numbers is

The product of two numbers is 2160 and their HCF is 12. If the sum of the squares of the two numbers is 4896, then what is the mean of the two numbers?

Two numbers are in the ratio of 3 : 5. Their L.C.M. is 90. The numbers are

Sum of the HCF and LCM of two numbers is 504 and LCM is 55 times of HCF. If one number is 99, then the second number is

Three number are in the ratio of 3 : 4 : 5 and their L.C.M. is 2400. Their H.C.F. is:
