A) 9660, 10080
B) 9320, 10080
C) 9660, 10060
D) 10340, 10080
Correct Answer: A
Solution :
The numbers which are exactly divisible by 2, 3, 4, 5, 6 and 7 are the multiples of the LCM of the given numbers. \[\therefore \] \[\text{LCM= 2}\times \text{2}\times \text{3}\times \text{5}\times \text{7=420}\] Now, dividing 10000 by 420, we get remainder = 340 \[\therefore \] Number just less than 10000 and exactly divisible by the given numbers = 10000 - 340 = 9660 Number just greater than 10000 and exactly divisible by the given numbers = 10000 + (420 - 340)=10080
