So given that, the board of length 40 inch divided into three parts, let the three part be the first part be of length x, the second part b of length y and the third part b of length z.
00:15
So the first conditions comes to be x plus y plus z.
00:20
It is some of all the length to be 40 inches.
00:25
Now, according to the question, it is given that the second.
00:30
Piece is twice as long as the first piece.
00:34
The second piece, so our second condition is the second piece that is y is twice as long as the first piece, two times long as the first piece, that is x.
00:44
And now our third condition given that the third piece is five times as long as the first piece.
00:52
The third piece that is said is five time as long as the five time as long as the first piece.
01:01
Now, substituting the value of equation 2 and 3 in 1...
