Solution for Quant Question of the day: 256
They meet after 6 days (lcm of 2 and 3) or after 6n days
and Wednesday will come after 3 days or 7k+3 days
so 7k+3 = 6n (where k and n are integers)
k = 3 , then, n =4
hence they will meet after 7(3)+3 = 24 days for first time on a wednesday
and then after 42 days (lcm of 6 and 7), they will again meet (for 2nd time) on a Wednesday. It means after 66 days Viraj will have 2 crystals.
