If a ⊕ b = L.C.M. of a and b, and a ⊗ b = G.C.D. of a and b, then (12 ⊗ 16) ⊕ (24 ⊗ 36) will be

The GCD of two numbers is 9 and LCM is 108. If one of the numbers is 27, then the other is

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

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?

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?

If x is the HCF and y is the LCM of 3/5, 6/25, 9/20, 27/50 then which one of the following is correct?
