Question

Neha is able to type 10 pages in 5 minutes. Garima can type 5 pages in 10 minutes. How many pages can they type together in 30 minutes?

Answer 1

Answer:

Naha's page in 5 minutes =10

garimas page in 5 min=2.5

both pages in 5 minutes =12.5

so boths pages in 30 minutes =12.5*6=75

Answer 2

Answer:

In 5 mins, Neha types 10 pages.

In 1 min, Neha types 10/5 pages = 2 pages.

In 30 mins, Neha types (2×30) pages = 60 pages

In 10 mins, Garima types 5 pages.

In 1 min, Garima types 5/10 pages = 1/2 page

In 30 mins, Garima types = (1×30)/2 pages = 15 pages.

Together they can type in 30 mins are

(60+15) pages

= 75 pages.
