Well...Sum Can be obtained by .... Coffecients..-1,0,1...
So All Values must be in Base 3....
From 3^0 to 3^6......So I got them.....
Also Remember In such type of questions..You should be aware of such shortcuts....

Happy Learning

Hey puys, this is my first post here. have been following the site for quite some time though. awesome site i must say..

Had a few queries with arun sharma from the chapter percentages.

Pg 158 Q.44.

A salesman is appointed with a basic salary of 1200/month and the condition that for every sales of 10000 and above he will get 50% of basic and 10% of sales. this scheme does not operate for first 10000 of sales. what would be the value of sales if he wants to earn 7600 in a particular month?

Pg 158 Q42

Aus scored X runs in 50 overs. india tied the score in 20% less overs. if indias avg run rate had been 33.33% higher the scores would have been tied 10 overs earlier. find how many runs were scored by australia.

A.250
B.240
C.200
D. Cannot be determined.

My Sol. I started solving the sum through options.

Aus----240----50overs----4.8
Ind-----240----40overs----6
ind-----240---30overs-----8 (6*4/3)
hence all conditions are fullfilled
Apparently as per the book the ans cannot be determined which i couldnt understand why??

Thanks.

Q 44) Is the answer 78,000 .. ?

Q 42) If the Aus scored, 'y' runs then,

40*r = y
And, 30*r*4/3 = y => 40*r = 30*r*4/3

Here, r could be any real number.

And, as you have more than one solutions to the problem the answer is 'cannot be determined'

....

please help me with the solution ...

q. what is the sum of factors of 18000 which are divisible by 8 but not by 25?

Let x*10000+10000 be the total sales.

Now 1000 x+ 600 * x= 7600-1200 = 6400
=> 1600 x = 6400
=> x = 4
Hence sale should be 10000*4 + 10000 = 50000

Is this correct?

Shouldnt India take 45 overs if it needs to score in 10% less overs?

[gamegeek98]

sorry that was a typo it was "india tied the score in 20% less overs"
The answer to Q44 was Rs.50000
although i still didnt understand the solution to the aust-ind sum.


Thanks a lot for the help puys

Two planes moving along a circle of circumference 1.2 km with constant speed.When they move in diffrent direction they meet every 15 secs and when they move in same direction one place overtakes the the other every 60 secs.Find teh speed of slower plane

please help me with the solution

please help me with the solution

Here..Let Speed of planes be a,b..both in m/s
Now...
(a+b)*15 = 1200..(1)
a+b = 80
Also
a*60 = 1200 + b*60
a-b = 20
So a = 50, b = 30 m/s
Answer = 30 m/s
