Answer 2

Answer:

Any multiple of 60 will be divisible by 10, 15 and 20.

10 x 6 = 60

15 x 4 = 60

20 x 3 = 60

60, therefore is the Least common multiple of numbers 10, 15, 20.

Now, the greatest 4-digit number is 9999.

So the number closest to (but less than) 9999 that is a perfect multiple of 60 will be the answer.

By checking all the multiples of 60 until it crosses 9999
