Explanation:

Alright, here’s how I’d lay it out:

- The question asks: How long will 20 men and 8 women take to finish the job?

- Statement I tells you how long 10 men and 8 women take, but with different manpower. Not enough for a direct answer.

- Statement II gives you days for 20 men and 4 women—but still, not the same team as the original question.

- By using both, you can set up equations with the two scenarios, since you have two unknowns (work rates for men and women). That lets you solve for their individual work rates, then plug them into your original scenario.

- Neither statement alone does the trick. But together? You can get to the answer.

Correct Answer: Option 3

What this really means is, you need both statements together—alone, they’re not enough. So if you went with Option 3, you nailed it.
