Hint: Assume the cost of scooter and cycle to be 9x and 5x respectively. Find out the difference between them and satisfy the condition given in the question.

Complete step-by-step answer:

According to the question, the prices of scooter and cycle are in the ratio $9:5$. Let the price of a scooter is $9x$ and that of a cycle is $5x$.

Given, the cost of scooter is Rs.4200 more than that of cycle. So, we have:

$

\Rightarrow 9x - 5x = 4200, \\

\Rightarrow 4x = 4200, \\

\Rightarrow x = 1050 \\

$

The value of $x$ is $1050$.

Then, the cost of the cycle is $5x = 5 \times 1050 = 5250$.

The cost of cycle is Rs.5250. (A) is the correct option.

Note: We can solve the question using the ratio and proportion method also.

The costs of scooter and cycle are in the ratio $9:5$. Thus, the difference between their costs is 4 ratios. And the difference between their costs is already given in question and it is Rs.4200.

So, 4 ratio is equivalent to 4200.

Hence, 1 ratio is equivalent to $\dfrac{{4200}}{4} = 1050$

And the cost of a cycle is 5 ratios. So, the cost of cycle is $5 \times 1050 = 5250$

The value of $x$ is $1050$.

Then, the cost of the cycle is $5x = 5 \times 1050 = 5250$.

The cost of cycle is Rs.5250. (A) is the correct option.

The costs of scooter and cycle are in the ratio $9:5$. Thus, the difference between their costs is 4 ratios. And the difference between their costs is already given in question and it is Rs.4200.

So, 4 ratio is equivalent to 4200.

Hence, 1 ratio is equivalent to $\dfrac{{4200}}{4} = 1050$

And the cost of a cycle is 5 ratios. So, the cost of cycle is $5 \times 1050 = 5250$
