28
Box contains marbles where red, white and green marbles. There are 3 less white marbles as compared to red marble, so we see that there are 13 red marbles in the box. There are 5 more white marbles as compared to green marble, so it is concluded that box contains 5 green marbles. Total number of white marbles is 10 Total number of marbles in the box will be addition of all the three which is 10+5+13 = 28. Hence we see that option B is correct.
