Question

The code word ${}^{\prime }10$7'$ for the word.

• A. Less
• B. Error
• C. And
• D. Fire
• E. None of these

Answer 1

The correct option is B Error

We can observe the following:
$\to$ First number of code :- (place value of last letter in reverse order ) + 1
$\to$ Symbol of code :- specified for number of letters in corresponding word as follows

3 letter word	&
4 letter word	%
5 letter word	$
6 letter word	*

$\to$ last number of code :- place value of first letter +2
(place value of 'a' is 1 and 'z' is 26 accordingly)
According to above conditions , code word for $10$7$mustbe$\Rightarrow$firstnumberofcode=$10-1=9\Rightarrow$9thplacevalueinreverseorder=$r\Rightarrow$itssymbolis$ so it is a 5 letter word
$\Rightarrow$Last number of code = $7-2=5$ $\Rightarrow$ 5th place value = $e$
Only option $B$ is satisfying given conditions.
