John wants to place marbles in carry bags and it is given that the bags can be empty too
(Hence, all the marbles can go to 1 bag also.)
It is given that there are 5 different marbles and 2 different bags.
Whatever is to be assigned, let’s make dashes for that.
M1 M2 M3 M4 M5
Number of ways to fill each dash = 2
Number of ways to fill 1st and 2nd and 3rd and 4th and 5th dash
= 2 × 2 × 2 × 2 × 2 = 32
Quantity A = 32
Quantity B = 25
Since, Quantity A is greater than Quantity B.
Ans. (A)


The phrasing is unclear; if I have M1 M2 in B1, and M3 M4 M5 in B2, is that not equivalent to having M1 M2 in B2, and M3 M4 M5 in B1? Shouldn't the result be 32/2 = 16 ?
