Weekly running schedule: Raju runs 1250 m on Monday and Friday, runs 1500 m on other weekdays and Saturday, and rests on Sunday. Starting Monday, how many kilometres does he run in 3 weeks?

Introduction / Context:This is a schedule-based arithmetic problem summing weekly distances over multiple weeks, with varying daily amounts and weekly rest days.

Given Data / Assumptions:

• Mon & Fri = 1250 m each
• Tue, Wed, Thu, Sat = 1500 m each
• Sun = 0
• 3 consecutive weeks starting Monday

Concept / Approach:Compute one-week total, then multiply by 3. Convert metres to kilometres at the end.

Step-by-Step Solution:

Verification / Alternative check:Counting days explicitly confirms 18 running days and 3 rest Sundays over 3 weeks.

Why Other Options Are Wrong:They reflect incorrect weekly totals or omission of rest days.

Common Pitfalls:Forgetting to include Saturday or excluding both Monday and Friday special distances correctly.

Final Answer:25.5 Km
