In a certain code language, ‘FONT’ is coded as ‘714’, ‘GLUE’ is coded as ‘494’. What is the code for ‘JOKE’ in that code language?

400

The logic here;

(Sum of the place value of first 2 numbers x Sum of the place value of las 2 numbers = Code of the word )

FONT = 714

F(6)+O(15)+N(14)+T(20)

= 21 x34= 714

Similarly,

JOKE = ?

J(10)+O(15)+K(11)+E(5)

= 25 x16= 400
