In a certain code language, ‘MASTER’ is coded as
'240', and 'LEADER' is coded as '186'. What is the code for 'BRIGHT' in that code language?Solution
The sum of all the place values of the letters as per the English alphabetical series is multiplied by '3' to get the coded number. MASTER = 13 + 1 + 19 + 20 + 5 + 18 = 76; 76 × 3 = 228 LEADER = 12 + 5 + 1 + 4 + 5 + 18 = 45; 45 × 3 = 135 BRIGHT = 2 + 18 + 9 + 7 + 8 + 20 = 64; 64 × 3 = 192 Thus, the code for BRIGHT is 192.
