Two teams participating in a competition had to take a test in a given...
Number of questions in the test taken by team A = 270
►Let team A answer x number of questions/hour for y hours
►Then xy = 270. Team B answers x + 7 questions for y - 3 hours
►Hence, (x + 7)(y – 3) = 300. Thus x = 18 and y = 15 or team A answers 18 questions per hour.

Two teams participating in a competition had to take a test in a given...
To solve this problem, we can start by finding the total number of questions each team had to answer and the time they had to complete the test.

Let's assume that team B had to answer x questions per hour and team A had to answer y questions per hour.

Total number of questions for team B = 300
Total number of questions for team A = 300 - (10/100) * 300 = 270

Let's calculate the time taken by each team to complete the test.

For team B, they completed the test 6 hours before schedule, so the time taken is:
300 / x = 6

For team A, they completed the test 3 hours before schedule, so the time taken is:
270 / y = 3

Now, let's solve these equations to find the values of x and y.

For team B:
300 / x = 6
300 = 6x
x = 50

For team A:
270 / y = 3
270 = 3y
y = 90

Therefore, team A answered 90 questions per hour.

So, the correct answer is option 'B', 18 questions per hour.
