A task is completed by 30 persons in 4 days. In how many days, the same will be completed by 40 persons?
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.
Mr. Qasim is 24 years older than his son Sajid. After 8 years, the age of Mr. Qasim will be twice the age of Sajid. What is the age of Mr. Qasim now?
Explanation:
Let's say Mr. Qasim's current age is x and Sajid's is y.
Mr. Qasim is 24 years older than Sajid: x = y + 24.
In 8 years, Mr. Qasim's age will be twice Sajid's: x + 8 = 2 (y+8).
Solving, we find y = 16 (Sajid's age) and x = 40 (Mr. Qasim's age now).
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?
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.
The population of Islamabad increased from 80000 to 100000 in the last two years. What is the percent of the increase in population?

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