A carpenter has to cut a piece of wood 5' long from a fallen tree. But
he has nothing with him to measure the wood except a piece of string.
There Lies adesk 3' x 7' which he has already made.

How will he be able
to accomplish his task?

Before you go for the answer please comment your answer!

First subtract the 7' from 3' there by you will get ans:4'

ReplyDeleteNow again subtract the ans:4' from previous 3' so you will get 1'.

So now 4'+1' =5' after that we can cut the wood

measure 3+3+3+3 and then measure 7 backward.... 12-7 =5'

Add 7+3 = 10

ReplyDelete10/2 = 5

Done.

I like your logic best.

Deleteadd 3+3+3+3=12 then subtract 12-7=5'

PRAKASH

With the string we measure 7' and fold it in half witch is 3 1/2' then we measure 3' and again folding the string in half witch is 1 1/2' + 3 1/2 = 5'
