Answer: Option B
Solution(By Examveda Team)
We go through otion picking method.
We first choose option b. Let B typed 128 pages.
So, Total time taken by B = 128 * 28 = 3584 min.
So, each have taken 3584 min.
No. of pages typed by A = 3584 /16 = 224.
No. of pages typed by C = 3584 /32 = 112
Now,
128 + 224 + 112 = 464.
So, option B is correct.
