CTET Paper I (Classes I to V) May 2016 Solved Paper

Concept:To compare time units, convert both sides to the same unit (seconds or minutes) using standard conversions: 1 day = 24 hours, 1 hour = 60 minutes, 1 minute = 60 seconds.Explanation:Check each option by calculating both quantities and comparing them.Option A: Seconds in 6 hours = $6 \times 60 \times 60 = 21600$ seconds. Minutes in 12 days = $12 \times 24 \times 60 = 17280$ minutes. $21600 \neq 17280$. False.Option B: Minutes in 15 days = $15 \times 24 \times 60 = 21600$ minutes. Seconds in 8 hours = $8 \times 60 \times 60 = 28800$ seconds. $21600 \neq 28800$. False.Option C: Minutes in 10 days = $10 \times 24 \times 60 = 14400$ minutes. Seconds in 6 days = $6 \times 24 \times 60 \times 60 = 518400$ seconds. $14400 \neq 518400$. False.Option D: Seconds in 2 hours = $2 \times 60 \times 60 = 7200$ seconds. Minutes in 5 days = $5 \times 24 \times 60 = 7200$ minutes. $7200 = 7200$. True.Answer:Option D is correct: The number of seconds in 2 hours is equal to the number of minutes in 5 days.
