Question

You decide to read 17 pages of a book by the end of the day, in the evening 9 pages are left to be read. How many pages have you read till evening?

• A. 8
• B. 6
• C. 9
• D. 7

Answer 1

The correct option is A 8

$\text{Detailed step-by-step solution:}$
Number of pages to be read = 17
Number of pages left to be read in the evening = 9
Number of pages read till evening = 17 − 9
We count back from 17 till 10 on the number line. The numbers we count are 16, 15, 14, 13, 12, 11, and 10, i.e. 7 numbers.
We need to count 9 numbers backward.
So, counting 2 more from 10—9, 8.
17 − 9 = 8


So, you have read 8 pages till evening.
