Question

A can copy 150 pages in 30 hours, A and B together can copy 280 pages in 35 hours. In what time would B copy 200 pages? please tell me correct answer step by step​

Answer 1

Answer:

The given data is about the time taken for each member (represented by alphabets) to copy some amounts of pages in a given time span.

A can Copy = 50 pages in = 10 Hours.

A and B together can copy = 70 pages in = 10 hours.

Given the same time span they've taken to copy different number of pages we can say that the second member that is "B" takes the credited time into the addition of "A and B" that is,

\bf{A + B = 70 \: \: Pages}A+B=70Pages

Since, the time span in cosiness of pages were same we'll just substitute the number of pages copied by the member "A" that is,

\bf{50 \: \: Pages + B = 70 \: \: Pages}50Pages+B=70Pages

\bf{B = (70 - 50) \: \: Pages}B=(70−50)Pages

\bf{B = 20 \: \: Pages}B=20Pages
