**Q.1 There are three ants at the three corners of a regular triangle. Each ant starts moving on a straight line toward another randomly chosen corner at the same speed. What is the probability that none of the ants collide?**

1/2

1/4

3/8

3/16

Answer : -

There will be no collision when the all the ants move in clock wise direction or anti clock wise direction.

From the ant’s perspective each can go left or right. There are 8 possible combinations – LLL, LLR, LRL, RLL, LRR, RLR, RRL, and RRR. You can also work that out by raising 2 (the number of choices) to the power of 3 (the number of choosers) = 2 x 2 x 2 = 8. In only 2 of these cases (LLL and RRR will there be no collisions, so 2 / 8 = 0.25

**Q 2. One number is 5 times another number and their sum is -60 (minus 60). What is the lesser of the two numbers?**

-10

-12

-48

-50

Answer: -

x = 5y

x + y = -60

So 5y + y = -60. 6y = -60, and y = -10.

If y = -10, x = 5y = 5(-10) = -50.

-50 is less than -10 , so (D) is correct.

**A dart board of radius 1 meter is at a distance of 20 meters from you. You throw a dart at it and it hits the dartboard at some point Q in the circle. What is the probability that Q is closer to the center of the circle than the periphery?**

2/5

3/4

1/2

1/4

Area related to points closer to center = 22/7 * 0.5 * 0.5

Area of entire circle = 22/7 * 1 * 1

Hence probability that Q is closer to the center = (22/7 * 0.5 * 0.5) / (22/7 * 1 * 1) = 0.25 or 1/4

**The average length of three ropes is 6800 feet. None of the ropes is less than 6600 feet. What is the greatest possible length of one of the other ropes?**

6800

7200

7600

8000

(x+y+z)/3 = 6800

Hence x+y+z = 20400 feet

To find the greatest possible length we should assume the other ropes are of minimum possible length which is 6600 feet. Let us assume z is the longest. Then,

x = y = 6600 feet

6600 + 6600 + z = 20400

so, z = 7200 feet

**It takes a cabin cruiser 3 hours longer to travel 50kms than it takes a power boat to travel 60kms. The cruiser travels half the speed of the power boat. Find the effective speed of power boat.**

40/3 kmph

32/13 kmph

28/3 kmph

54/5 kmph

let 2x = speed of power boat. Then x is the speed of cabin cruiser.

50/x = 60/2x +3. solving x=20/3 kmph.

So power boat effective speed = 2x = 40/3 kmph
