Morshed has d books, which is 3 times as many as Salain and 1/2 as many as Roni. How many books do the three of them have altogether, in terms of d?

A 5d/6

B 10d/3

C 7d/3

D 9d/2

Solution

Correct Answer: Option B

If morshed has = d books.

Salain has = d/3 books

And, Roni has = 2d books

Together they have = d + 2d +d/3 books

= (3d + 6d +d)/3 books

= 10d/3 books
