A scanning unit scans 270 pages in 3/4 hour. How many pages will be scanned in 2.5 hours ?
900
The scanning rate is found by dividing the number of pages by the time taken.
\(\text{Rate} = \frac{270}{3/4} = 270 \times \frac{4}{3} = 360\) pages per hour.
For 2.5 hours, the pages scanned are \(360 \times 2.5 = 900\)
Hence, 900 pages will be scanned in 2.5 hours.

The ratio of two numbers A and B is 5 : 8. If 5 is added to each of A and B, then the ratio of A and B becomes 2 : 3. The sum of A and B is:
The ratio of two numbers A and B is 5: 8. If 5 is added to each of A and B, then the ratio becomes 2 : 3. The difference between A and B is:
A sum of Rs. 6342 is divided amongst A, B, C and D in the ratio 3 : 4 : 8 : 6. What is the difference between the shares of B and D?
The ratio of monthly incomes of A and B is 4 ∶ 5 and that of their monthly expenditures is 3 ∶ 8. If the income of A is equal to the expenditure of B, then what is the ratio of savings of A and B?
The ratio of the monthly incomes of A and B is 11 : 13 and the ratio of their expenditures is 9 : 11. If both of them manage to save Rs. 4,000 per month, then find the difference in their incomes (in Rs.)
