Directions: The question is based on the following pie chart.
Project implementation cost of ABC Ltd. (Rs. Crores)
Total project cost = Rs. 252 Crores

If the plant cost increases by 5% due to increase in construction cost, what will be approximate angle of the plant sector in the pie chart?
Detailed Solution for VITEEE PCBE Mock Test - 6 - Question 21

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 $\displaystyle \frac{73.5\times 360}{255.5}$ = 103.6° (Approx)

VITEEE PCBE Mock Test - 6 - Question 22
Save

Directions: The question is based on the following pie chart.
Project implementation cost of ABC Ltd. (Rs. Crores)
Total project cost = Rs. 252 Crores

If there is an escalation of 10% in Salaries& Wages and a reduction of 10% in land, what will be the new angle of salaries and wages?
Detailed Solution for VITEEE PCBE Mock Test - 6 - Question 22

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°

VITEEE PCBE Mock Test - 6 - Question 23
Save

Directions: The question is based on the following pie chart.
Project implementation cost of ABC Ltd. (Rs. Crores)
Total project cost = Rs. 252 Crores

If 5% of administrative costs are reduced and 10% of the remaining administrative costs are transferred to Others category, what is the angle of administrative costs now?
Detailed Solution for VITEEE PCBE Mock Test - 6 - Question 23

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°

Directions: The following diagrams show the cost price and selling price (in Rs.) of different fruits sold by a fruit vendor.

How much percentage profit can he earn from the apples?
Detailed Solution for VITEEE PCBE Mock Test - 6 - Question 24

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 = $\displaystyle \frac{Profit}{C.P.}\times 100$ =  × 100 = 59% (approx.)

After the division of a number successively by 3, 4 and 7, the remainders obtained are 2, 1 and 4 respectively. What will be the remainder if 84 divides the same number?
Detailed Solution for VITEEE PCBE Mock Test - 6 - Question 28

Since after division of a number successively by 3, 4 and 7, the remainders obtained are 2, 1 and 4 respectively, the number is of form ((((4*4)+1)*3)+2)k = 53K.

Let k = 1; the number becomes 53

If it is divided by 84, the remainder is 53.

Therefore, the correct answer is Option D.

VITEEE PCBE Mock Test - 6 - Question 29

Teacher said that there were 100 students in his class, 24 of whom were boys and 32 were girls. Which base system did the teacher use in this statement?
Detailed Solution for VITEEE PCBE Mock Test - 6 - Question 29

We are provided with the equation (32) + (24) = (100). Let us assume our base be 'b'
Then,we can say:

⇒ 32 = 3 x b1 + 2 x b0 = 3b+2
⇒ 24 = 2 x b1+ 4 x b0 = 2b+4
⇒ 100 = 1 x b2 + 0 x b1 + 0 x b0 = b2

Now, according to our question:

⇒ 32 + 24=100
⇒ (3b + 2) + (2b + 4) = (b2)
⇒ 5b + 6 = b2
⇒ b2 - 5b - 6 = 0
⇒ b2 - 6b + b - 6 = 0
⇒ b(b - 6) + 1(b - 6) = 0
⇒ (b - 6) * (b + 1) = 0
⇒ b = 6,- 1

Base can't be negative. Hence b = 6.
∴ Base assumed in the asked question must be 6.
