M=30*P/100,Q=20*P/100,N=50*P/100
M/N=((30*Q)/100)/((50*P)/100)=((30*20*P)/100*100)/((50*P)/100)=3/25

. There are 10 stepping stones numbered 1 to 10 as shown at the side. A fly jumps from the first stone as follows; Every minute it jumps to the 4th stone from where it started - that is from 1st it would go to 5th and from 5th it would go to 9th and from 9th it would go to 3rd etc. Where would the fly be at the 60th minute if it starts at 1?

as it is given that fly will start from 1 then jump to 5 then 9.
so,following this pattern for every three min. there a series
1 5 9 for first 3 min.
3 7 1 (6 min)
5 9 3 (9 min)
7 1 5 (12 min)
9 3 7 (15 min)
1 5 9 (18 min)
it is clear that this series is repeating after 15 min.
so 60/15=4. hence after completing the above series upto 15 min. 4 times. on 60th min fly will be on 7th stepping stone.
so. Ans is 7

your answer is A(1).from your question I assume all 10 stepping stones are laying in a circle.
since, there are 10 stones in a circle so, each stone makes 360/10=36degree b/w any two stones.
now, a/c to your question, fly makes 4*36=144degree per minute.
so,after 60 minute it makes 60*144=8640degree.
now, we all know that 360degree makes at a point, i.e, if we move on a circle and when we make 1 full round then we make 360degree.
now, when fly makes 8640degree it makes 8460/360=24 full round. means at 60th minute fly in on the initial point i.e, it is on 1st stone.

A box contains 10 balls numbered 1 through 10. Anuj, Anisha and Amit pick a ball each, one after the other, each time
replacing the ball. What is the probability that Anuj picks a ball numbered less than that picked by Anisha, who in turn picks
a lesser n

Reply Like? Yes (3) | No (2)

(11 years ago)

anuj has equal probability to pick higher or lower....
so 1/2

Like? Yes (3) | No (12)

(9 years ago)

If Amit picks up 10 and Anisha picks up 9 then

(10, 9, 1) (10, 9, 2) .... (10, 9, 8) - 8 ways
(10, 8, 1) (10, 8 2) ..... (10, 8, 7) - 7 ways

8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 8(9)/2 = 36

If Amit picks up 9 then

(9, 8, 1) ..... (9, 8, 7) ... = 7 ways
7 + 6 + 5 + 4 + 3 + 2 + 1 = 7(8)/2 = 28

For 8 - (6)(7)/2 = 21

For 7 - (5) (6)/2 = 15

For 6 - (4) (5)/2 = 10

For 5 - (3) (4)/2 = 6

For 4 - (2) (3)/2 = 3

For 3 - (1) (2)/2 = 1

1 + 3 + 6 + 10 + 15 + 21 + 28 + 36

You either add them or apply the expression n(n+1)(n+2)/6 which is the sum of triangular numbers =8(9)(10)/6 = 120

WHAT JITENDRA PRASAD HAS EXPLAINED IS CORRECT EXCEPT THE LAST PART. TOTAL NUMBER OF OUTCOMES WILL BE (10* 10 * 10) . SO WE WILL GET THE ANSWER BY DIVIDING 120/1000 i.e 3/25.

Like? Yes (14) | No

(8 years ago)

The balls are numbered as 1,2,3,4,5,6,7,8,9 and 10.
If 1 numbered ball picks up by Anuj then Anisha will picks up 2 or 3 or 4 or ..... or 10 = 9 ways.
like this,
2 numbered ........................... = 8 ways.
3 numbered ............................ = 7 ways.
.
.
.
9 numbered................................ = 1 way
So, number of ways that Anuj picks a ball numbered less than that picked by Anisha = 9+8+7+6+5+4+5+4+3+2+1 = 45 ways
Amit picked a ball from remaining 8 balls = 8c1 = 8 ways
one ball lesser from 3, that is 3c1
number of possible ways = (45*8)/3= 120
Total number of possible ways = 10c1 * 10c1 *10c1 = 1000
The probability = 120/1000 = 3/25

You can assume through the option that if you add 4 in both 12 and 44 than we get 16 and 48 which satisfied the condition

option a 12 n 44

Like? Yes (1) | No

(11 years ago)

ans :a) 12 yrs, 44 yrs
father's age=x
son's age=y
x+y=56 ->equation 1
after 4 years (x+4)=3(y+4) ->equation 2
from equation 1 we will get y=56-x
substitute y value in equation 2
x+4=3((56-x)+4)
x+4=168-3x+12
x+3x=180-4
4x=176
x=176/4
x=44 -> Father's age
then substitute y value to equation 1
44+y=56
so we get y=56-44
son's age y=12

305 in base 2 has 9 digits.....so he can divide the number in half going from 305 to 1(i.e. Deepak Sharma) = 9*2 = 18

Like? Yes | No

(11 years ago)

305/2 => 152 => 76 => 38 => 19 => 9 => 4 => 2 => 0 Up on Successive division by 2 for 305 entries, we end up in 0 after 9 intervals. and each takes 2 mins to answer hence 9*2=18

It is actually based on Binary search. Since, the numbers are in alphabetical order of names, she can call the last number and ask his name. Based on the response, she picks up 305/2 = 152 nd number. Then, 152/2 = 76 th number, then 76/2 = 38th number, 38/2 = 19 th number, 19/2 = 9th number, 9/2 = 4th number, 4/2 = 2nd number, 2/2 = 1st number. So, she has to make minimum 9 calls. Each call duration is 2 minutes. So, she takes 18 minutes.

One day Eesha started 30 min late from home and reached her office 50 min late while driving 25% slower than her usual speed. How much time in min does eesha usually take to reach her office from home?

Reply Like? Yes (1) | No

(11 years ago)

60 min or 1 hr.

as,
let her usual speed be 's' and time be 't'.
then, on the day, her speed is = .75*s
and time is = t + (20/60) hr
so,
s*t = .75 s * (t+1/3)
implies t = 1 hr.

Like? Yes | No

(11 years ago)

let her usual speed x and time taken for it is y
now his speed is x-(x/4)=3x/4 and time taken for it is y+20
:. x/(3x/4) = y+20/y
thrfr y =60 min

Like? Yes (1) | No

(11 years ago)

she usually takes 60 min to reach her office.
In actual Esha reached her office 20 min late due to her slow speed because she already left home 30 min late that day.
50-30=20
let her usual speed is x and her usual time taken to reach office is y.then on that very day her speed reduces by 25% i.e, her speed is 3x/4 and she takes (y+20)min
so, we get y=60 min.

Like? Yes | No

(11 years ago)

Let y be the distance from home to office
Let x be the usual time taken
Let u be the usual speed
therefore new speed= u-u/4=3u/4
u=y/x.......eq1
new time x'=x+20
so 3u/4=y/x+20.......eq2
Substituting eq1 and 2
3x+60=4x
therefore, x=60 answer

357 is divisible by 17 so that remainder is 5

Like? Yes | No

(11 years ago)

let x be the number
as x leaves remainder 5 when divided by 357
so x=357a+5
here a is the qoutient
when number is divided by 17 we get
x/17 = (357a+5)/17 = 21a+5/17
