hi

i abruptly remember one Q frm di frm the foreign trade table...

it says the percentage increase of exports-imports from yr 2004-2005 to 2005-2006

[ashish_rathi]

a+b+c+d+e=10
a+b,b+c,c+d,d+e X is the maximum of dese.
Find the mininum value of X..my take would be ans is 4.ie when a=b=c=d=e=2.


find the max value of b/a.
1.a,a+b,a+2b are the three (sides or angles) of a triangle.
2.a and b are positive

i marked cannot be answered by using bo the statements together.

I agree with you, the answer is 4. The only problem was that among the options there were 2 options which included 4 i.e [3,4] and [4,5]. I think answer would be [4,5] since the answer has to be greater than 4. Quant gods please confirm

i dont remember the ans for 3*4 matrix one....
i did it by (adding 1-15)-6-8

cause those were the no.s missing(6 and
since 3*4 matrix has 12 no.s ....
1 more no had to be eliminated from the given no.s....

hence (106-x) should be divisible by 12....
hence x is 10.....

Let p and q be positive nos.
On day one some person covered 1/p of the distance AB,2nd day 1/q of the remaining distamce,3rd day 1/p of the remaining distance and 4th day 1/q of the remaining distance.After 4th day,3/4th of the total distance was covered.

1.Find the value of p+q
Ans 7

2.Find the minimum distance covered on day one if the total distance was 100 Ans 25
