Solution:

325 pages and 585 pages assignments are to be finished in the exact number of days.
CONCEPT:HCF:
The greatest number which divides each of the two or more numbers.
CALCULATION:
Since we have to find the greatest number thus we have to find the HCF.

325 = 5 × 5 × 13585 = 3 × 3 × 5 × 13

⇒ HCF of 325 and 585 = 5 × 13 = 65
∴ Boy should type 65 pages per day.
