Question 1

In a certain code language 'allow children to play on the ground' is written as 'play allow on children the to ground' then how will 'the do open not electric touch wires ' be coded from that language?

Accepted Answer

For convenience , we assign numbers to each word : allow children to play on the ground 1 2 3 4 5 6 7 It has been coded as : play allow on children the to ground 4 1 5 2 6 3 7 ------------------------------------------------------------------------ Hence the given code is : the do open not electric touch wires 4 1 5 2 6 3 7 Now arranging them as 1 2 3 4 5 6 7, we have "do not touch the open electric wires'. Hence, option (3) is correct answer.
