Question 6 of 10

6. Question

1 points

Category: Quantitative Aptitude

Directions (6-8): In each of the following questions, a question is followed by three statements numbered I, II and III. Read all the statements and answer accordingly.

What will be the increase percent in volume?
Statement I: An ice cube is dip into 10 litre water
Statement II: If radius of a cylinder increases by 20% and height increases by 10%
Statement III: If the height of ice cube is 10 cm.

Correct

Solution: Volume = π*r*r*h
So by successive formula, the increase in volume can be found
First: r*r
So 20 + 20 + (20)(20)/100 = 44%
Next: 44 + 10 + (44)*(10)/100 – final increase in volume
From I and III:
volume of given shape (cylinder, cube, cone etc) = 10 l (initial volume). And ice cube of height 10 cm is dip into it.
So after finding new volume or increase in volume after the ice cube is dipped, % increase in volume can be found.

Incorrect

Solution: Volume = π*r*r*h
So by successive formula, the increase in volume can be found
First: r*r
So 20 + 20 + (20)(20)/100 = 44%
Next: 44 + 10 + (44)*(10)/100 – final increase in volume
From I and III:
volume of given shape (cylinder, cube, cone etc) = 10 l (initial volume). And ice cube of height 10 cm is dip into it.
So after finding new volume or increase in volume after the ice cube is dipped, % increase in volume can be found.

Statement II: If A and B can do the work in 15 days

Correct

Solution: From I. 30/A + 10/B=1
from II. 1/A + 1/B=1/15. We can get A and B using both

Question 9 of 10

9. Question

1 points

Category: Quantitative Aptitude

Direction for Question 9-10: In the following question, two statements are numbered as I and II. On solving these statements you get Quantity I and Quantity II respectively. Solve for both the statements individually and mark the correct answer.

A rectangular plot measuring 80 meters by 40 meters is to be enclosed by wire fencing along the boundary of the plot. The fence will be tied on poles that will be placed along the boundary.

Quantity I: Number of poles required for fencing if each pole is at a distance of 24 meters.
Quantity II: Radius of a circle whose area is 10% of the area of the rectangular plot.

Correct

Solution: I: Perimeter= 2(80+40)=240
No. of poles = 240/24=10
II: Area of circle = 320 =>22/7*r*r=320
r=101.81 => r >10
Hence II > I

Incorrect

Solution: I: Perimeter= 2(80+40)=240
No. of poles = 240/24=10
II: Area of circle = 320 =>22/7*r*r=320
r=101.81 => r >10
Hence II > I

Question 10 of 10

10. Question

Correct

Solution: I: 7C2/9C2=7/12
II: A-> 10 days => fraction of work in 7 days = 7/10
Hence II > I

Solution: I: 7C2/9C2=7/12
II: A-> 10 days => fraction of work in 7 days = 7/10
Hence II > I
