What is the greatest number of 4-digits which is divisible by 45, 25 and 5?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 9900.
LCM of 45, 25, and 5 = 225
Divide 9999 (the largest 4-digit number) by 225
By dividing 9999 by 225, we get quotient = 44 and remainder = 99
Therefore, the largest 4 digit number = 9999 - 99 = 9900
