score. Alisha's English score is 15 less than Elizabeth's English score. Dolphy's Math score is 20 more
than his English score and is 20 more than Carey's Math score. Dolphy's Math score is 40 more than

parul srivastava 11 years ago

answer is 7 days
a does 10% of work
b does 8.33% of work
c does 6.66% of work
total work done by a+b+c is 25% of work
in 2 days a+b+c work together 2*25% work completed=50% work done
therefore total time required is =2*(a+b+c)+2*(b+c)+3*(b)
hence by solving answer is 7 days

A circle has 29 points arranged in a clockwise manner numbered from 0 to 28, as shown in the figure below. A bug moves clockwise around the circle according to the following rule. If it is at a point i on the circle, it moves clockwise in 1 second by ( 1 + r ) places, where r is the reminder ( possibly 0 ) when i is divided by 11. Thus if it is at position 5, it moves clockwise in one second by ( 1 + 5 ) places to point 11. Similarly if it is at position 28 it moves ( 1 + 6 ) or 7 places to point 6 in one second. If it starts at point 23, at what point will it be after 2012 seconds?

We can see a pattern emerging in the point positions from the 3rd second
onwards…1, 3, 7, 15, 20 and then the cycle keeps repeating. After 5 s, 10 s, 15 s,
the bug’s position is 7. So after 2010s, the position should be 7. The position
after 2011s is 15, and after 2012s it is 20.

3 sec 0 0 1+0 0+1=1

6 sec 7 7 1+7=8 7+8=15
7 sec 15 4 1+4=5 15+5=20

9 sec 1 1 1+1=2 1+2=3
10 sec 3 3 1+3=4 3+4=7
and so on this process continue up to end
so 3 sec, 8 sec, 13 sec, 18 sec, and so on ............2008 sec later the position is 1 position,
2009 sec the position is 3,
2010 sec the position is 7,
2011 sec the position is 15
2012 sec the position is 20

what is the ans... 3.8??

Like? Yes | No

Lovey 11 years ago

A beats B by 15m & B beats C by 10m.... It means A beats C by 25m
So distance is 25m and time is 5 sec for C as C is chasing A by 25m in 5sec
therefore speed of C= distance/ time -> 25m/5sec = 5m/sec
hence, speed of C= 5m/sec

Like? Yes | No

Nomendra Sinha 11 years ago

ans=4.7 m/s
When B is at finish line(100m) difference B-C=10m
So when B is at (100-15)m difference B-C=10*85/100=8.5m
means A-C=(A-B)+(B-C)=15+8.5=23.5m
so C cover 23.5m in 5 sec means speed=23.5/5=4.7 m/sec

=a^3x+a^2b+ab+b
a^3x+b(a^2+a+1)
given that is equal to 8x+21
by comparing we ger a^3=8 which implies a is 2
and by substiting we get b=3

X-intercept means y,z coordinates are zero.
so X-intercept is (54/7,0,0)
Z-intercept means x,y coordinates are zero.
So z-intercept is (0,0,54/3)
The diStance between two points is (18/7)*(58)^1/2.But there is no answer.If I am wrong Please let me know.

Ratio and if the final mixture is 35 liters, find the amount of b?

Reply Like? Yes | No

Inline Geek 11 years ago

a:b = 3:5 = 24:40 (intentionally multiplied with 8)
b:c = 8:5 = 40:25 (intentionally multiplied with 5)

so a:b:c = 24:40:25

b has 40 parts out of 89 (i.e. 35 liters)

so b in liters = 35 * 40 / 89
= 15.73 liters

Like? Yes (1) | No

Nomendra Sinha 11 years ago

a:b:c=3*8 : 5*8 : 5*5 = 24:40:25
total 24+40+25=89 part =35 litres
so 40 part = 40*(35/89) =15.73 litres
