f the ration of a b and c 's earning are 2:3:5.if a increases his earning by certain amount while b increases by double of that amount and c increases by thrice of that amount then what could be the ratio of a and c's earning?

A supplier shipped a lot of 5 parts to a company. the lot contained 2 defective parts. Suppose the customer decided to randomly select 2 parts and test them fr defects. Suppose the customer decided to randomly select 2 parts and test them for defects. List the sample space. Using the sample space list, determine the probability that the customer will select a sample with exactly one defect.
remainder of [ (12!)^14! + 1] / 13 ?
someone please prove wilsons theorem?????
I have just started doing Probability .. shunned so far . so here is my question -please explain properly
1. A number is chosen at random from first 300 natural numbers, What's the probability that the number so chosen is divisible by 3 or 5 ?
2. A number is chosen at random from first 100 natural numbers . What's the probability that the number is divisible by 2 or 3 or 5 ?
Thanks in advance! 👍
chirag was celebrating her B'day. Her friend asked her to cut the cake in such a way that we get max pieces with 6 cuts. Find the no of max pieces?
I don know the OA. Please share your approach as well. Thank you..
A circle is divided into 8 sectors and they are named as S1, S2, …, S7, S8 in anticlockwise manner with the numbers 1, 2, 3, 4, 5, 6, 7 and 8 written in them respectively. You are allowed to change the numbers in the sectors with the following rules in mind. One move constitutes changing the numbers in any two consecutive sectors. The numbers in two consecutive sectors can be increased or decreased only by the same amount. However numbers in any two different pairs of sectors need not be increased or decreased by the same amount.For example in one move numbers in sectors 1 and 2 can be increased or decreased by 3 each and in another move numbers in sectors 3 and 4 can be increased or decreased by 6 each. Can you make moves in a way such that finally all eight sectors have the same number ...in them?
OPTIONS
1) Yes. It will take at least 16 moves.
2) Yes. It will take at least 8 moves.
3) Yes. It will take at least 32 moves.
4) No.
5) Yes. It will take at least 64 moves.
plzz also post the approach and explanation.....

Hey, does anyone have any PDF or other files with all the formulas of Quant ? If you have something, can you please mail it to me ? It would be really helpful for me.
My e-mail is cool_blogger@ymail.com
Anyone ? 😃
From Quantexpert mocks:
The following system of equations have exactly 11 real roots:
| x | = 2;
| y+2 | = 4;
x^2 + (y+4)^2 = r^2;
What is the value of r?
(a) 3
(b) 4
(c) 5
(d) 6
This question has been bothering me for 10 min 😛
Need approaches (short-cuts)
a+b+c+d+e+f = 300
(given f>e>d>c>b>a) all integers and positive
find the number of possible solutions ?
This question looks simple on face but i am not able to deduce the approach.
A tool is developed by the company and after many uses following status has been established.
1% of the transactions marked by the tool as erroneous were actually correct.
1% of the transactions marked by the tool as good transactions were actually erroneous.
If the entry marked by the tool is errorneous, find the probability that it is actually erroreneous?
If the entry marked by the tool is error free, find the probability that is actually free?
If the entry marked by tool is error free, find the probability that it is actually erroneous?
Need complete approach as last time i have come across similar question in cat also😠
plz puys solve and explain it!!!!!!!!!!!
Hi guys , this question is from IMS Simcat 4 , I attempted it today only , so late in posting :
Area of Region |x-7|+|y-9|=12..
I know answer is 288 but can someone just give me detailed approach that how would Diagonals would be 24 in length like in case of |x| + |y|=12 when the graphs of two equations are different?
A man takes a step forward with probability=0.4 and backward=0.6, The probability that he is 1 step away after 11 steps is??
