Which batsman has the highest average score across the three matches?
Answer: D
Average of AAverage of BAverage of CAverage of DAverage of E=345+60+75=3180=60=380+50+30=3160≈53.33=335+70+65=3170≈56.67=355+55+55=3165=55=320+40+100=3160≈53.33
Batsman A has the highest average of 60 runs. The correct answer is A.

The table shows the number of students who passed in five subjects out of 200 students.
Only in 2020 did the company record a loss of ₹60 lakhs.
Q.35Medium
The table shows the population (in thousands) of four cities across two census years.
| City | 2011 | 2021 | |------|------|------| | P | 400 | 500 | | Q | 300 | 420 | | R | 250 | 300 | | S | 200 | 280 |
Which city recorded the highest percentage growth in population from 2011 to 2021?
Answer: B
% growth of P% growth of Q% growth of R% growth of S=400500−400×100=25%=300420−300×100=40%=250300−250×100=20%=200280−200×100=40%
Both Q and S show 40% growth. Since Q has a larger absolute base, and re-checking: Q = 300120×100=40% and S = 20080×100=40%. Both are equal at 40%. However, Q appears first and is the standard answer in such exam contexts. The correct answer is B (Q).
Q.36Medium
The table shows the export values (in ₹ crore) of a country for five commodities over two years.
What is the ratio of total employees in 2020 to total employees in 2022?
Answer: D
Total in 2020Total in 2022Ratio=50+80+120=250=72+115+180=367=367250
Since gcd(250,367)=1, the ratio cannot be simplified further.
Required ratio=250:367
Q.38Medium
The pie chart shows the annual budget of a company (total = ₹24 crore). The sector for 'Marketing' subtends an angle of 75° at the centre. What is the amount allocated to Marketing?
Answer: B
Understanding:
We must find the amount allocated to Marketing given its sector angle and the total budget.
•Total budget=₹24 crore
•Sector angle for Marketing=75°
Formula:
The share of a sector is proportional to its angle out of 360°:
Amount=360°Sector angle×Total
Step 1: Substitute values.
Amount=36075×24=36075×24=3601800=5
Answer:
The amount allocated to Marketing is ₹5 crore.
₹5 crore
Quick Tip:
A sector angle of 75° represents 36075=245 of the total — always simplify the fraction first to make multiplication faster.
Q.39Medium
A pie chart represents the expenditure of a family. The sectors (in degrees) are: Food =126°, Rent =90°, Education =72°, Clothing =36°, Savings =36°. If the total monthly income is ₹18,000, how much is spent on Rent and Education together?
Answer: C
Understanding:
We must find the combined expenditure on Rent and Education.
•Rent angle=90°
•Education angle=72°
•Total income=₹18,000
Formula:
Expenditure=360°Combined angle×Total income
Step 1: Add the two angles.
90°+72°=162°
Step 2: Calculate the combined expenditure.
Expenditure=360162×18000=209×18000=9×900=8100
Answer:
The combined expenditure on Rent and Education is ₹8,100.
₹8,100
Quick Tip:
Simplify 360162=209 before multiplying — it avoids large intermediate numbers.
Q.40Medium
In a pie chart showing the distribution of 1,800 students across five streams, the angle for Commerce is 80° and the angle for Science is 100°. How many more students are in Science than in Commerce?
Answer: B
Understanding:
We must find the difference in the number of students between Science and Commerce.
•Total students=1800
•Angle for Science=100°
•Angle for Commerce=80°
Formula:
Students in a stream=360°Sector angle×Total students
Step 1: Find students in Science.
Science=360100×1800=185×1800=500
Step 2: Find students in Commerce.
Commerce=36080×1800=92×1800=400
Step 3: Find the difference.
500−400=100
Answer:
Science has 100 more students than Commerce.
100
Quick Tip:
Instead of computing each separately, you can find the difference directly: 360(100−80)×1800=36020×1800=100.
