What will be the answer? And how?

Dear student,

Total number of red balls = 222

Now, 6 red balls are drawn from this lot

So, number of times 6 balls are drawn from the lot =  

We are given that every time 6 red balls are replaced with 12 white balls in the lot and we know from above this replacement is done 37 times. 

So, total number of white balls = 37 × 12 = 444

Therefore option (B)
