Answer 1

580 is the number divisible by 24, 25 and 120, when increased by 20

Step-by-step explanation:

Let x be the number.

Then x + 20 divisible by 24, 25 and 120.

LCM of 24, 26 and 120

24 = 2 * 2 * 2 * 3

25 = 5 * 5

120 =  2 * 2 * 3 * 2 * 5

LCM = 2*2*2 * 3 * 5 * 5

    = 8 * 3 * 25

LCM = 600

So the number x will be 600 - 20 = 580
