Dear Manish sir,
In the question ,A toy train can make two musical sound..........
your sol. is as follows...
only two different tunes are there, so for making 5 consecutive music tunes of the same type, probability = (1/2)(1/2)(1/2)(1/2)(1/2)*2 = 1/16
last 2 is because of the two case (1) first tune all 5 times (2) second tune all 5 times
but here the question is based on odds, so answer should be (1/16)/[(1-(1/16)] = 1/15

dear sir , help me to understand 1) multiplication by 2...... as we r not choosing musical sound , 1/2 is the prob. of selecting one sound out of given two sounds
2) how this question is based on odds

Ans: 15%

The difference b/w the compound interest and the simple interest over 2 years=P*(r/100)^2
P*(r/100)^2=405;
18000(r/100)^2=405;

20. Two trains, each 100 m long are moving in opposite directions. They cross each other in 8 seconds. If one is moving twice as fast the other, the speed of the faster train is

A. 75 km/hr

B. 60 km/hr

C. 35 km/hr

D. 70 km/hr

Hide Answer|Notebook | Discuss
Here is the answer and explanation

Answer : Option B

Explanation :

Total distance covered = 100+100 = 200 m

Time = 8 s

let speed of slower train is v . Then the speed of the faster train is 2v

(Since one is moving twice as fast the other)

Relative speed = v + 2v = 3v

3v = 200/8 m/s = 25 m/s

=> v = 25/3 m/s

Speed of the faster train = 2v = 50/3 m/s = (50/3)×(38/15) km/hr = 5×36/3 = 5×12 = 60 km/hr

let distance be d and time interval be t

distance covered by tom in one jump=d/7
distance covered by jerry in one jump=d/5

time taken by tom for one jump=t/8
time taken by jerry for one jump=t/6

speed=distance/time

toms speed=(distance covered in one jump)/(time taken for one jump)
=(d/7)/(t/8)=8d/7t
similarly,
jerrys speed=(d/5)/(t/6)=6d/5t

toms speed/jerrys speed=(8d/7t)/(6d/5t)=40/42

after 4 days , 1200 soldiers will have sufficient food for 28-4 = 24 days
but 300 soldiers left and so 900 remain in palace, therefore food will last for (24 * 1200)/900 = 32 days

a boat can travel 10.2km upstream in 51 minutes. if the speed of the current is 1/5 of the speed of he boat in still water, how much distance can the boat traveled downstream in 48 minutes?

Reply Like? Yes (1) | No

Devendra Marghade 8 years ago

14.4 km.

If speed of the boat=x kmph, then speed of the current=x/5 kmph and upstream speed=x-(x/5)=4x/5
As boat can travel 10.2 km upstream in 51 minutes, so 10.2/(4x/5)=51/60 ,x=15
So speed of the current=x/5=15/5=3 kmph and downstream speed=15+3=18 kmph
Distance that boat can travel in 48 minutes or 4/5 hours =18*4/5=14.4 km

If initially there were 2a & 3a balls in bag x and bag y respectively, then
3a-5=2a+5

So number of balls in each bag now=3a-5 or 2a+5 =25

let r1 be the radius of larger disk r2 be the radius of small disk

pi (r1)² /pi(r2)² =9/1

r1/r2 =3/1

let r1 =3x and r2 = x

2 *pi*r1 = 6pix
2*pi *r2 =2pix

perimeter are in the ratio 3:1

therefore small disc rotate 3 times in one rotation of larger disc
