In a certain code language, BANKER is coded as 57 and SPAN is coded as 54. How will PRANK be coded in that language?

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

THE LOGIC FOLLOWED HERE IS :

SUM OF THE POSITIONAL VALUE + TOTAL NUMBER OF LETTER

NOW

BANKER = TOTAL NUMBER OF LETTER = 6

B = 2

A = 1

N = 14

K = 11

E = 5

R = 18

2 + 1 + 14 + 11 + 5 +  18  = 51

SUM OF THE POSITIONAL VALUE + TOTAL NUMBER OF LETTER

51 + 6 = 57

AND,

SPAN

SPAN  = TOTAL NUMBER OF LETTER = 4

S = 19

P = 16

A = 1

N = 14

19 +  16 + 1 + 14  = 50

 SUM OF THE POSITIONAL VALUE + TOTAL NUMBER OF LETTER

50 + 04 = 54

SIMILARLY

PRANK

PRANK  = TOTAL NUMBER OF LETTER = 5

P = 16

R = 18

A = 1

N = 14

K = 11

16 +  18 + 1 + 14 + 11  = 60SUM OF THE POSITIONAL VALUE + TOTAL NUMBER OF LETTER

60  + 5  = 65
