Question

In a certain code, DOWN is written as 5139 and NEAR is written as 9486. How is RODE written in that code ?

• A. 6514
• B. 6154
• C. 9154
• D. 3154
• E. None of these

Answer 1

The correct option is B 6154

In a certain code, DOWN is written as
$D\to 5O\to 1W\to 3$
$N\to 9$ ...(i)
and NEAR written as
$N\to 9E\to 4A\to 8$
$R\to 6$ ...(ii)
From Eqs. (i) and (ii), RODE is written as
$R\to 6O\to 1D\to 5E\to 4$
