In a certain code language, '254' means 'You are intelligent', '153' means 'Nikhil is intelligent', '398' means 'Naina and Nikhil', then what is the code for 'is' in the same code language?

'254' ==> 'You are intelligent'

'153' ==> 'Nikhil is intelligent'

'398' ==> 'Naina and Nikhil'

In the first and second statements, 'intelligent' is common. So the code for this will be '5'.

In the second and third statements, 'Nikhil' is common. So the code for this will be '3'.

Now in the second statement only 'is' is remaining which will be coded as '1'.

So '1' is the code for 'is' in the same code language.
