Answer 2

Answer:

Time to take type 150 pages is 11 hours 30 minutes.

Step-by-step explanation:

First we have to calculate,

A can type how many pages in 1 hour

=) 30/4 = 7.5

B can type how many pages in 1 hour

=) 35/6 = 5.8

Now both A and B work together to type 150 pages

Let us assumpt : Time taken for A and B to do 150 pages is T

Then calculation is

=) (7.5+5.8) × T = 150

=) (13.3)×T =150

=)T = 150÷13.3

=) T=11.278

Conclusion is :

There fore Time taken by A and B both for typing 150 pages is 11 hours 27 minutes.

Our answer is approximately near to (Option number 1). i.e. 11 hours 30 minutes.

Answer is 11 hours 30 minutes.
