#CAT   #CAT2016   #2iim  
CAT Quant question from geometry triangles. A very important topic, and a common question pattern. Learn from Rajesh Balasubramanian, 100 percentiler in CAT 2011, 2012 and 2014.

Permutation Probability
A boss decides to distribute Rs. 2000 between 2 employees. He knows X deserves more that Y, but does not know how much more. So he decides to arbitrarily break Rs. 2000 into two parts and give X the bigger part. What is the chance that X gets twice as much as Y or more? 
a.2/5
b.1/2
c.1/3
d.2/3

PROBABILITY AND NUMBER THEORY

N is a 3-digit number that is a multiple of 7; what is the probability that it will be a multiple of 5?
a.1/5
b.11/54
c.13/64
d.13/66
#CAT2016   #CAT  
Detailed Solution. N is a three digit multiple of 7. N could be 105, 112, 119, 126…..994. Or, 15 × 7, 16 × 7…..142 × 7. Or there are 142–14 = 128 numbers. Within these we need to locate the multiples of 5. Or, we need to isolate multiples of 35. Or, we need to see how many numbers there are in ...

Detailed Solution. First A.P., a = 1, d = 4 S2n = 2n/2 [2 x 1+(2n −1)4] S2n = n(2 + 8n – 4) = n(8n – 2) = 8n2 – 2n For the second AP, a = 56, d = 2 Sn = n/2 [2 x 56+(n −1)2] Sn = n/2 [112+2n −2] = n/2 (110+2n) The sum of 2n terms of AP {1, 5, 9, 13, …..} is greater than sum of n terms of A.P. ...
