Neither R nor V travels in Skoda. Also no girl travels in same car in which person wearing White coloured dress travels. V is wearing Blue coloured dress From the above statements, we can conclude: 
The product of two numbers is 504 and their HCF is 6. Total number of such pairs of numbers is?  Â
What is the unit digit of the sum of 3694 and the product of 214 and 123?
If the product of two numbers is 90 and their HCF is 6, then find the LCM of the given two numbers.
- Three numbers are in the ratio 3:5:7 respectively. If the HCF of the numbers is 4, then find the LCM of the numbers.
Let N be the greatest number that will divide 89, 110, 131 leaving the same remainder in each case. Then sum of the digits in N is:
Let N be the greatest number that will divide 85, 116, 147 leaving the same remainder in each case. Then sum of the digits in N is:
The least number which when divided by 10, 12, 15 and 20 leave zero remainder in each case and when divided by 24 leaves a remainder of 12 is:
