Question

8. What is the greatest number of digits which if increased by 3, it becomes
divisible by 35, 45, 55 and 60.​

Answer 1

Answer:

Step-by-step explanation:

35 = 5x7

45 = 5x9

55 = 5x11

60=5x4x3

so LCM of these is 4x5x7x9x11 = 13860

so you want the largest 6 digit number where 3 more than it divides by that number

999999 / 13860 = 72.15, so go for 72 x 13860, and subtract 3, and that is your answer (997920)
