Question

Abhishek Jain typed 50 pages at the rate of 30 pages per hour on Sunday. On Monday, he could only type 50 extra pages at the rate of 20 pages per hour. What has his average rate of typing been overall. Calculate in pages per hour?

Answer 1

Answer:

No. of hours Abhishek typed on Sunday = 50 = 5

30 3

No. of hours Abhishek typed on Monday = 50 = 5

20 2

Total hours of typing = 5 + 5 = 25

3 2 6

Total pages typed = 50 + 50 = 100

Average rate of typing = 100 = 6 × 4 = 24

25

6

Hence, Abhishek Jain typed 24 pages per hour.

Answer 2

Given:

On Sunday:

Pages typed= 50;

Rate = 30 pages/hr

On Monday:

Pages typed=50

Rate=20 Pages/hr

To Find:

Average typing rate.

Solution:

Time taken on Sunday=$\frac{total pages}{rate}$

                                     =$\frac{50}{30}$

                                     =$\frac{5}{3} hrs$

Time taken on Monday=$\frac{total pages }{rate}$

                                      =$\frac{50}{20}$

                                      =$\frac{5}{2} hrs.$

Total Pages =$50+50$

                    =$100$

Total Time= $\frac{5}{3} +\frac{5}{2}$

                 =$\frac{25}{6} hrs.$

Average rate= $\frac{total pages}{total time}$

                     =$\frac{100}{\frac{25}{6} }$

                     =$24$

Hence Average Rate of Typing is 24 pages per hour.
