Pie Chart Questions for CAT with Answers PDF

Given plant cost = (100°/360°) × 252 crores = 70 crores
Plant cost increases by 5% of 70 crores = 3.5 crores.
∴ The Plant cost would be = 73.5 crores
∴ The total project cost would be 252 + 3.5 = 255.5 crores
Now, 255.5 is equivalent to 360°
∴ 73.5 will be  = 103.6° (Approx)

New angle of Salaries & Wages = 55° x 1.1 = 60.5° = 55 + 5.5
New angle of Land = 55° x 0.9 = 49.5° = 55 - 5.5
Since the increase in Salaries & Wages is the same as the decrease in Land, there will be no change in the total angle of the pie chart.
Thus, new angle of salaries and wages = 60.5°

Reduction in administrative cost 5% of 30° = 1.5°
Hence, remaining administrative cost = 30° - 1.5° = 28.5°
Transferred administrative cost 10% of 28.5° = 2.85°
∴ Hence, the remaining administrative cost 28.5° - 2.85° = 25.65°
Also, since 5% of the administrative costs (1.5°) are reduced, thus new pie angle = 360° - 1.5° = 358.5°
Hence, new angle of Administrative Cost = x 360 = 25.76°

Cost price of apples = 35% of Rs. 11,500 = Rs. 4025
Selling price of apples = 40% of Rs. 16,000 = Rs. 6400
Profit = Rs. 6400 - Rs. 4025 = Rs. 2375
So, profit percentage =  =  × 100 = 59% (approx.)

Only on grapes will he suffer a loss.

C.P. is constant.
S.P. of pineapple is increased by 20%; the contribution of pineapple in total S.P. is 15%.
If we assume total S.P. to be 100, then
Increase = 20% of 15 = 3
Out of total 100, increase ⇒ 3%

Runs scored by Kohli = (6 x 0.04 + 1 x 0.48 + 2 x 0.20 + 3 x 0. 06 + 4 x 0.22) x 50 = 109 
So, strike rate =  = 73.65 = 74 (approx.)

Kohli's share = 

Team's total score = (0.52 x 1 + 0.22 x 2 + 0.04 x 3 + 0.20 x 4 + 0.02 x 6) x 150 = 300
Total number of balls = 
= 300/0.75 = 400
Total number of balls = 400
Thus, number of dot balls = 400 - 150 = 250

Team's total score = (0.52 x 1 + 0.22 x 2 + 0.04 x 3 + 0.20 x 4 + 0.02 x 6) x 150 = 300
Dhoni's score = 43 runs
Runs scored by Kohli = (6 x 0.04 + 1 x 0.48 + 2 x 0.20 + 3 x 0. 06 + 4 x 0.22) x 50 = 109 
Contribution of Kohli and Dhoni in total run's = 

Income from college is Rs. 40 lakhs.
Let total income be Rs. x.
40% of x = 40 lakhs
x = (40/40) x 100 = 100 lakhs
Let total expenditure be Rs. y. 
55% of y = 11 lakhs
y = (11/55) x 100 = 20 lakhs
Total savings of relief fund = 100 - 20 = Rs. 80 lakhs

From given information,
Total income = Total expenditure - 9% of total expenditure
= Total expenditure - 6,50,000
Total expenditure = 6,50,000/0.09 = Rs. 72,22,222 (approximately)
Total income = 72,22,222 x 0.91 = Rs. 65,72,222 (approximately)

Income from college = Expenditure on taxes and amenities
⇒ 40% of income = 36% of expenditure
Expenditure = 

Relief fund's contribution = 35% of the total income
Total income =  28,57,143
Savings = Rs. 60,000
⇒ Total expenditure = Total income - savings
= 28,57,143 - 60,000 = 27,97,143
Expenditure on salaries of workers = 55% of total expenditure = Rs. 15,38,429

Initial Savings of F = 2,70,000 x 0.2 – 1,45,000 x 0.24 = 54,000 - 34,800 = Rs. 19,200
Final Savings of F = 2,70,000 x 0.2 x 1.18 – 1,45,000 x 0.24 x 1.36 = 63,720 - 47,328 = Rs. 16,392
Percentage decrease = (2808 x 100)/19,200 = 14.6%

Amount saved by B = 2,70,000 x 0.21 – 1,45,000 x 0.15 = 56,700 - 21,750 = Rs. 34,950
Amount saved by D = 2,70,000 x 0.21 – 1,45,000 x 0.18 = 56,700 - 26,100 = Rs. 30,600
Required Percentage = (34,950 x 100)/30,600 = 114.22%

Total expenses are $150 mn.
Since the companay got 20% profit, so the income will be $180 mn.

Both bicycles and bikes gives 50 % profit.

Total expenses are $150 mn.
Since the company got 20% profit, so the income will be $180 mn.

Total expenses are $150 mn.
Since the company got 20% profit, so the income will be $180 mn.

Expenses of cars increased by 10%.
New expenses of cars = 54 x 1.1 = 59.4 mn
Increase in expenses of cars = 59.4 - 54 = 5.4 mn
Total expenses increase = 150 + 5.4 = $155.4 mn
10% decrease in income of bikes (30%)
New income of bikes = 54 x 0.9 = 48.6 mn
Decrease in income of bikes = 54 - 48.6 = 5.4 mn
Hence, total income = 180 - 5.4 = $174.6 mn
New profit = $174.6 - $155.4 = $19.2 mn
Initial profit = $30 mn
So, decrease in profit % = [(30 - 19.2)/30] x 100 = 36%
