G(6)= g(5)+g(4)g(4)= g(3)+g(2)g(2)= g(1)+g(0)= 2 (Given in ques g(0)=g(1)=1)So, g(3)= g(2)+g(1)= 2+1= 3Also, g(4)= g(3)+g(2)= 3+2= 5Similarly, g(5)= g(4)+g(3)= 5+3=8And hence, g(6)= g(5)+g(4)= 8+5= 13 -ANS

The answer should be 33.5 As there are two equation L+H=100andL=1/3 + 1/2(H)so we getL= 1/3 + 1/2(L-100)Which gives L= 33.5 approx.

- Aug 30th, 2010
From 1 to 40 there are 37 possible combinations of 4 consecutive numbers.
Total number of possible combinations= 40C4.
Probability of outcome to be consecutive = 37/(40C4)= 1/2470
Probability of outcome not to be consecutive = 1-(1/2470)= 2469/2470

4 km/hr from A to B = s1
8 km/hr from B to A = s2
Speed = Distance/Times1 = d1/t1
s2 = d2/t2
s1/s2 = t2/t1 We need t1/t2 so,
Answer ratio is 2:1

In a mixture, R is 2 parts S is 1 part. In order to make S to 25% of the mixture, how much r is to be added?
One Part
velusara
- Nov 19th, 2010
Ans = R should be added with 50%If r is 2 parts S is 1 part i.e 2/1 = 1 or 1+1 = 2so if s increases by 25% of 1 then it is 1.25 + 1.25 = 2.5 that is r
Prashant202185
- Sep 24th, 2008
Since R= 2 parts and S = 1 parts so % of s = 1/3*100 = 33.33%Let x of r is added to make S to 25%then 1/(3+x)*100 = 25 => 75+25x=100 so x= 1 ans

Min-Max Game
A and B play the following min-max game. Given the expressionN = 12 + X*(Y - Z)where X, Y and Z are variables representing single digits (0 to 9), "A" would like to maximize N while "B" would like to minimize it. Towards this end, "A" chooses a single digit number and "B" substitutes this for a variable of her choice (X, Y or Z). "A" then chooses the next value and "B", the variable to substitute the...
