Guys, tell me something.
If a train "crosses" a bridge, what exactly does it mean in terms of length (distance travelled) ?
A and B start a two-length swimming race at the same moment but from opposite ends of the pool. They swim in lane and at uniform speeds, but A is faster than B. They first pass at a point 18.5 m from the deep end and having completed one length, each one is allowed to rest on the edge for exactly 45 seconds. After setting off on the return length, the swimmers pass for the second time just 10.5 m from the shallow end. How long is the pool ? approach please...!!!
- 55.5 m
- 49 m
- 66 m
- 45 m

Hey guys confused about how to find the maximum value of a quadratic equation ax^2+bx+c=0 when a
4ac-b^2/4a or x=-b/2a
thanks in advance
A sum doubles itself in one year at a certain rate of interest, compounded annually. In how many years will a sum become six times itself under the same investment scheme?
Let P be the sum
2P=P (1+ r/100)^1
Let (1+r/100)=R
2=R---------(1)
Also, from 2nd
6P=PR^n
R^n=6-----2
from 1 and 2 , 2^n=6
taking log both sides (base 2)
n log 2 (base 2) = log 6 (base 2)
n=log 6 (base 2)
But the ans =2.5 yrs. error in my approach ?

Consider all pairs of polynomials (f(x),g(x)) with complex coefficients such that
f(x) is a monic polynomial of degree 3 and has distinct roots α1,α2,α3.
g(x) is a linear polynomial such thatg(α1)=α2, g(α2)=α3, g(α3)=α1.
f(0)=2.
f(1)=9.
The sum of all possible (distinct) values of f(2) is N. What are the last three digits of N?
