Question
In a certain code language, HAMMER is coded as 5 and
MINOR is coded as 135. What is the code of word ‘DANCING’ in the same coding language?ÂSolution
The pattern followed here is as follows: Product of the place value of second letter and second last letter. In HAMMER → Place values of A and E are 1 and 5, respectively. 1 X 5 = 5.  In MINOR → Place values of I and O are 9 and 15, respectively 9 X 15 = 135 Similarly, in DANCING → Place values of A and N are 1 and 14, respectively 1 X 14 = 14.
