Question : 18 of 200

Marks: +1, -0

If CERTAIN is coded as 610922185 and HEADING is coded as 16102818514, then how will RENTAL be coded ?

Solution:

The pattern followed is:-
When place value is single digit, it is multiplied with 2.

If the place value is double digit, the digits are added.

\table C,E,R,T,A,I,N;(3),(5),(18),(20),(1),(9),(14); ↓3×2,↓5×2,↓1+8,↓2+0,↓1×2,↓9×2,↓1+4;6,10,9,2,2,18,5

\table H,E,A,D,I,N,G ;(8), (5), (1) ,(4) ,(9) ,(14), (7) ;↓8×2,↓5×2,↓1×2,↓4×2,↓9×2,↓1+4,↓7×2;16,10,2,8,18,5,14

Similarly,

\table R,E,N,T,A,L; (18),(5), (14) ,(20),(1),(12); ↓1+8,↓5×2,↓1+4,↓2+0,↓1×2,↓1+2;9,10,5,2,2,3

So, RENTAL is coded as 9105223.
Hence, the correct answer is "9105223".
