correct answer is: 05:04 Explanation: The ratio of the time taken by the two trains to cross a pole is determined by the ratio of their lengths divided by their respective speeds. For the first train, the time is $\frac{5}{2}$ units, and for the second train, it is $\frac{6}{3} = 2$ units. Simplifying the ratio $\frac{5}{2} : 2$ gives $5:4$ OPTION a (05:04): Correct, as derived above. OPTION b (07:04): Incorrect, as it does not match the calculated ratio. OPTION c (02:07): Incorrect, as it inverses the correct ratio. OPTION d (05:07): Incorrect, as it does not match the calculated ratio. Akhilesh ? answered Apr 2 '25 at 23:24
