A board of length L feet is cut into two pieces such that the length of one piece is 1 foot more than twice the length of the other piece. Which of the following is the length, in feet, of the longer piece?
(A) \(\frac{L + 2}{2}\)
(B) \(\frac{2L +1}{2}\)
(C) \(\frac{L-1}{3}\)
(D) \(\frac{2L+ 3}{3}\)
(E) \(\frac{2L+1}{3}\)
In this type I prefer to use number; however there are other ways to solve it -
Let
B = smaller side = 3
A = Larger side = 1 + (2*3) = 7
So the total length = 10.
Put the value of L in the option and we need 7 as an answer. Only option E yields the correct answer.
It is also advisable to start substituting the number L from option C as we will come to know whether we need to proceed towards option A or to option E.
