In a certain code language, 'feel at home' is coded as ' 424 ', 'check the laundry' is coded as ' 537 ' and 'open the door' is coded as ' 434 '. How will 'the kite is flying' be coded in that language?

3426

Given; In a certain code language, 'feel at home' is coded as ' 424 ', 'check the laundry' is coded as ' 537 ' and 'open the door' is coded as ' 434 '. 

The logic;

(the code is given according to the letters present in a word)

So,

1)  'feel at home' is coded as ' 424 '

feel -> 4

at -> 2

home -> 4

And,

2)  'check the laundry' is coded as ' 537 '

check -> 5

the -> 3

laundry -> 7

3)  'open the door' is coded as ' 434 '

open -> 4

the -> 3

door -> 4

Similarly,

 'the kite is flying' .....?

the -> 3

kite -> 4

is -> 2

flying -> 6

Thus, 3426 is correct.
