SOLUTIONS

1.Answer : 2. Quantity II > Quantity III > Quantity I
Explanation-
Let the cube’s edge length is a, the surface area of cube = 6a^2 and its volume = a^3.
Let the radius of the sphere is r, then its volume = (4/3) Ï€r^3 and its surface area will be 4Ï€r^2.
Let the height of the cylinder be 2h therefore, its radius will be h.
Surface area of the cylinder = 2Ï€h (2h) +2Ï€h^2 = 6Ï€h^2.
Now since the surface area are same, 6a^2 = 4Ï€r^2 = 6Ï€h^2, therefore, r= (√3/√ (2Ï€)) a.
Volume of sphere = (√6/√Ï€)a^3, this will be always greater than a^3.
Hence Quantity II > Quantity I, Also 6a^2 = 4Ï€r^2 = 6Ï€h^2, a = (√Ï€)/h.
Volume of the cylinder = Ï€h^2(2h) = 2Ï€h^3 = 2Ï€(a/√Ï€)^3 = 2a^3/(√Ï€) > a^3.
Hence Quantity III > Quantity I. Volume of sphere = (√6/√Ï€) a^3 is > volume of the cylinder = 2a^3/ (√Ï€).
Hence, Quantity II > Quantity III > Quantity I

2.Answer : 4. Quantity III > Quantity II > Quantity I
Explanation-
Quantity I: 6*9/(50C2) = 54/1225.
Quantity II = 1- 45C3/(50C3)= 1 – 14190/19600 = 541/1960 > Quantity I .
Quantity III = 1 – 41C3/(50C3)= 1 – 10660/19600 = 894/1960 > Quantity II > Quantity I.
Hence, Quantity III > Quantity II > Quantity I

3.Answer : 2. II alone and I and III together
Explanation-
Volume = Ï€*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.

4.answer : 4. None of these
Explanation-
Data is not sufficient to find the number of failed students in class 6.

5.Answer : 3. Quantity II > Quantity I
Explanation-
Solution: I: 7C2/9C2=7/12
II: A-> 10 days => fraction of work in 7 days = 7/10
Hence II > I

Explanation

Total student in D who watch FRIENDS are 300, student selected for state level quiz is 40% of 300=120
For national level is 25% of 120=30
Total student who watch FRIENDS are 150, for state level quiz 33(1/3)% of 150= 50, for national level are two fifth of 50 is 20
Total student from both colleges selected for national level quiz are 50

Explanation
Total no of student who watch SUITS= 200+300+250+150+100=1000
Total no of students who watch GOT=250+100+150+200+350=1050
1000/1050=95.23

Explanation
Students selected for state level from college B = 16(2/3)% of 300=50
Students selected for state level from college D = 6(2/3)% of 150=10
Students selected for state level from college E = 20% of 100= 20
Total = 50+10+20= 80
