Question 73
The least number which should be added to 2497 so that the sum is exactly divisible by 5, 6, 4 and 3 is:
Solution
L.C.M. of 3,4,5,6 = 60
On dividing, 2497 by 60, we get :
=> $$2497 = (60 \times 41) + 37$$
Thus, the least number which should be added = $$60 - 37 = 23$$
Now, 2497 + 23 = 2520 is divisible by 60
=> Ans - (C)
