RRB Technician Grade 1 Model Paper 4

Concept:Each pair follows the rule: left number is the square of a number, and right number is the reverse of the cube of that same number.Explanation:For $225 - 5733$:$225 = 15^2$$15^3 = 3375$Reverse of $3375$ is $5733$, so this pair follows.For $169 - 7912$:$169 = 13^2$$13^3 = 2197$Reverse of $2197$ is $7912$, so this pair follows.For $361 - 9786$:$361 = 19^2$$19^3 = 6859$Reverse of $6859$ is $9586$, but the given right side is $9786$.So this pair does not follow the rule.For $289 - 3194$:$289 = 17^2$$17^3 = 4913$Reverse of $4913$ is $3194$, so this pair follows.Answer:Option C: $361 - 9786$ is the odd one out.
