If a clock takes 22 seconds to strike 12 times (uniform intervals), how long will it take to strike 6 times?

Introduction / Context:For striking clocks, the count of intervals equals (strikes − 1). Time scales with intervals if the interval length is constant.

Given Data / Assumptions:

• 12 strikes → 11 intervals → 22 s total.

Concept / Approach:Interval = 22/11 = 2 s. For 6 strikes → 5 intervals.

Step-by-Step Solution:Time = 5 * 2 = 10 seconds.

Verification / Alternative check:Proportional reasoning is straightforward.

Why Other Options Are Wrong:12 s and 14 s assume wrong interval counts; 9 s ignores uniformity.

Common Pitfalls:Using 6 instead of 5 intervals for 6 strikes.

Final Answer:10 seconds
