Question
Let N be the greatest number that will divide 85, 112,
139 leaving the same remainder in each case. Then sum of the digits in N is:Solution
To find the greatest number that leaves common remainder in each case, The HCF of (112-85), (139-85), (139-112) = 27 In this case the number will be 27. And sum of digits will be = 9
The LCM of x and y is 2057 and their HCF is 23. If x = 187, what will be the value of y?
