The sum of two numbers is 1224 and their HCF is 68. The number of pairs of numbers satisfying the above condition is: |
3 4 6 2 |
3 |
The sum of two numbers is 1224 and their HCF is 68 Let the two numbers be x and y respectively x + y = 1224 HCF is 68 So, let x = 68a and y = 68b , ( m + n) then 68m + 68n = 1224 ⇒ 68 ( m + n ) = 1224 ⇒ ( m + n) = 18 The required numbers are ( 1,17), ( 5,13), ( 7,11) = 3 |
