Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

A person can $\sf en co de$ 1000 words in every hour of typing job.

Which of the following expresses the total works W as a function of the number n of hours that the person can $\sf en co de$

a) W(n) = 1000n

b) W(n) = 1000 + n

c) W(n) = 1000 - n

EVALUATION

Here it is given that the person can $\sf en co de$ 1000 words in every hour of typing job.

Now W = Total work

n = The number of hours that the person can $\sf en co de$

So by the given condition

W = Number of hours × Number of word $\sf en co de$ in 1 hour

⇒ W = n × 1000

⇒ W = 1000n

Since W is a function of n

So we have W(n) = 1000n

FINAL ANSWER

Hence the correct option is a) W(n) = 1000n
