In triangle ABC, BE is drawn so that E lies on AC, and AD is drawn so that D lies on BC. AD and BE intersect inside the triangle at F. The area of ABC is 1, BD = DC and AE/EC = 2. What is AF/FD?
4:1 hai kya?

haan.. A and B are numbers..

are bhai mera matlab..A* B nai hai na...AB hai(10A+B) types?/

@nick_baba said:
An integer N, 100
N = 125?

100 400 144 91
N is divisible by 5
144 100 100 121
Combining 121N = 125

Remainder when N is divided by 7 = 6

p x r^2 /100 = diff
p = 360 x 10000/900 => 4000
