Question

Ram reads 17 pages of a book per day. Estimate the number of pages he will read in the month of March?
(By rounding off to the nearest tens)

• A. 300
• B. 450
• C. 600
• D. 430

Answer 1

The correct option is C 600

Number of days in the month of March = 31

Ram reads 17 pages per day.

So, number of pages he will read in 31 days =$17\times 31$

We’ve to calculate this by rounding off each number to its nearest tens.

17 will be rounded off to 20.
31 will be rounded off to 30.

Estimation for $17\times 31$ will be $20\times 30=600$

So, option 'c' is correct.
