Answer 2

Answer:

The correct answer is 8

Step-by-step explanation:

From the above question,

They have given :

In an office of 50 people, 18 write with their right hand, 26 write with their left hand and 2 can write with both hands.

Total number of people in the office = 50

Number of people who can write = 18 (right - handed) + 26 (left  -handed) + 2 (both hands) = 46

Number of people who can't write = Total quantity of human beings in the workplace - (Number of humans who can write + Number of humans whose writing hand is unknown)

Here we need to find how many cannot write.

                   = 50 - ( 18 + 26 - 2 )

                   = 50 - 42

                   = 8

So the correct answer is 8
