Concept:The second number is obtained by multiplying the first number by the fixed factor 3.8.Apply the same operation to both sides of the ratio.Explanation:Given the pattern X:68.4 and 22:Y, the rule is:Second number=First number×3.8For the left pair, substitute X as the first number and 68.4 as the second number:X×3.8=68.4Solve for X:X=3.868.4​=18So X=18.Now apply the same rule to the right pair:Y=22×3.8Calculate the product:Y=83.6Thus both pairs follow the identical pattern using multiplication by 3.8.Answer:The correct values are X=18 and Y=83.6, which matches Option C.
