The diameter of a cylindrical tin is 6cm and height is 5 cm. Find the volume of the cylinder?

A. 30 π cc
B. 45 π cc
C. 150 π cc
D. 180 π cc
r = 3 h = 5
π * 3 * 3 * 5 = 45 π cc

A person can row at 9 kmph and still water. He takes 4 1/2 hours to row from A to B and back. What is the distance between A and B if the speed of the stream is 1 kmph?

A person can row at 9 kmph and still water. He takes 4 1/2 hours to row from A to B and back. What is the distance between A and B if the speed of the stream is 1 kmph?

A. 32 km
B. 25 km
C. 28 km
D. 24 km
E. None of these
Explanation:
Let the distance between A and B be x km.
Total time = x/(9 + 1) + x/(9 – 1) = 4.5
=> x/10 + x/8 = 9/2 => (4x + 5x)/40 = 9/2 => x = 20 km.

The current of a stream at 1 kmph. A motor boat goes 35 km upstream and back to the starting point in 12 hours. The speed of the motor boat in still water is_________?

The current of a stream at 1 kmph. A motor boat goes 35 km upstream and back to the starting point in 12 hours. The speed of the motor boat in still water is_________?

A. 6 kmph
B. 7 kmph
C. 8.5 kmph
D. 8 kmph
Explanation:
S = 1
M = x
DS = x + 1
US = x – 1
35/(x + 1) + 35/(x – 1) = 12
x = 6

If four coins are tossed, the probability of getting two heads and two tails is__________?

A. 3/8
B. 6/11
C. 2/5
D. 4/5
Explanation:
Since four coins are tossed, sample space = 24
Getting two heads and two tails can happen in six ways.
n(E) = six ways
p(E) = 6/24 = 3/8

A. 120
B. 180
C. 200
D. 280
Explanation:
80* 7: x* 3 = 1:1 1/2
560: 3x = 2: 3
x = 280
