Arun makes a popular brand of ice-cream in a rectangular shaped bar 6 cm long 5cm wide and 2 cm thick. To cut costs the company had decided to reduced the volume of bar by 19%. The thickness will remain the same, but the length and width will be decreased by the same %. The new width will be

A6.5

B5.5

C7.5

D4.5

Explanation:

Volume = l*b*h
=> 6*5*2 = 60cm^3
Volume is reduced by 19%
New Volume = (100-19)100*60 = 486000 = 48.6
Thickness is same but length and breadth reduces by x%
So,new volume = (x/100*6)(x/100*5)2 = 48.6
=> x=90
So, Length and Breadth reduced by 10%
=> new width = 5-(10 * 5/100) = 4.5

A conical tent is to accommodate 10 persons. Each person must have 6 sq.meter space to sit and 30 cubic meter of air to breathe. What will be the height of the cone?

A150m

B37.5 m

C15 m

D75 m

Explanation:

Amount of area reqd. by 1 person to stand = 6 sq.metre
Amount of area reqd. by 10 person to stand = 6x10 sq.metre i.e 60 sq.metre
So,
Base Area, pi*r*r=60
=>r*r = 60/pi ---------------(1)
Now,
Volume of air reqd. to breathe 1 person= 60 cu.metre
Volume of air reqd. by 10 person to breathe = 60x10=600 cu.metre
So,
Volume, 1/3*pi*r*r*h = 300 ---------------------(2)
Putting the value of eqn 1 in eqn 2, we get
1/3*pi*60/pi*h = 300
=> 1/3*60*h = 300
=> 20*h = 300
=> h = 300/20 = 15
Therefore height = 15 metres

A solid iron cylinder of radius 4 cm and height 18 cm is melted and recast into a sphere. What is the radius of the sphere?

A4 cm

B6 cm

C18 cm

D9 cm

E12 cm

Explanation:

volume of cylinder = pi * r^2 * h
volume of sphere = 4/3 * pi * r^3
as cylinder is melted therefore volume of both will remain same therefore equating both we get
r^3=216
=> r = 6 cm

The section of a solid right circular cone by a plane containing vertex and perpendicular to base is an equilateral triangle of side 10 cm. find the volume of the cone?

A221.73 cm3

B223.73 cm3

C228.73 cm3

D226.61 cm3

Explanation:

Volume of the cone = 1/3 (PI*R*R*H)

Since the cone is formed from by an equilateral triangle, all sides are equal that is slope = diameter = 10

So, height = (10^2) - (5^2) = ?75 [by hypotenuse theorem]
=> Height = 8.66

Volume = 1/3(8.66*3.14*25)

=> Volume = 226.61 cm^3
