In a certain code language, 'TANK' is coded as ‘4' and 'PIR' is coded…

1   2    3    4   5    6   7     8    9  10  11  12  13

 A   B   C    D   E    F   G    H    I    J    K    L   M

26  25  24  23  22  21  20  19  18  17  16  15  14

*********************************************

THE LOGIC FOLLOWED HERE IS :

NUMBER OF ALPHABETS GIVEN IN THE WORD IS CODE GIVEN

SO TANK = 4

THERE ARE FOUR ALPHABETS IN THE WORD

AND,

PIR = 3

THERE ARE THREE ALPHABETS IN THE WORD

SIMILARLY

FREIGHT = 7

THERE ARE SEVEN ALPHABETS IN THE WORD

HENCE CORRECT OPTION IS 4
