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.

  1. lets total people be 100 those who grad be x now those who did not…(100-x)
    boys=0.4x+70-0.7x
    70-0.3x=60
    x=100/0.3
    (option approach is easier)
