Question 1

An alarm beeps 16 times per minute. How much time will it take to beep 88 times?

Accepted Answer

5.5 minutes

Answer

Explanation:
The alarm beeps 16 times in one minute. To find out how long it takes for 88 beeps, we divide 88 by 16. The result is 5.5 minutes.

Question 2

A task is completed by 30 persons in 4 days. In how many days, the same will be completed by 40 persons?

Accepted Answer

3

Answer

Explanation:
30 people take 4 days to complete the task, which totals 120 "man-days." To find out how many days 40 people would take, we divide the total man-days (120) by the number of people (40), which equals 3 days.

Question 3

The average mark of Shahid in the first four papers is 88. How many marks should he get on the fifth paper so that the average of all five papers becomes 90?

Accepted Answer

98

Answer

Explanation:
To find the marks Shahid should get on the fifth paper, we first need to calculate the total marks he has obtained in the first four papers. Since the average mark of Shahid in the first four papers is 88, the total marks he has obtained in these four papers is 4 × 88 = 352.

Now, to achieve an average of 90 in all five papers, the total mark he should have in all five papers is 5 × 90 = 450.

To find the marks needed on the fifth paper, we subtract the total marks he already has (352) from the desired total marks (450).

450 − 352 = 98

So, Shahid should get 98 marks on the fifth paper.

Question 4

Considering the following two equations, what is the value of a + b?
a + 4 = 10
b + 10 = 4

Accepted Answer

0

Answer

Explanation:
To find the values of 𝑎 and 𝑏, we can solve the equations:
a + 4 = 10
b +10 = 4

From the first equation, we find that a = 6.
From the second equation, we find that b = −6.

Therefore, a + b = 6 + (−6) = 0.

Question 5

What percent of 40 is 16?

Accepted Answer

40%

Answer

Explanation:
To find what percent of 40 is 16, divide 16 by 40 and then multiply by 100 to get the percentage:

16/40 × 100 = 40%
