Problem Analysis:
We are given that 5 men or 7 women earn a total of 275. We need to find out how much 10 men and 13 women will earn.

Calculating the earning of 1 man and 1 woman:
To find out how much 1 man earns, we can divide the total earning by 5 since 5 men earn 275.
Earning of 1 man = 275 / 5 = 55.

Similarly, to find out how much 1 woman earns, we can divide the total earning by 7 since 7 women earn 275.
Earning of 1 woman = 275 / 7 ≈ 39.29.

Calculating the total earning of 10 men and 13 women:
Now, we can calculate the total earning of 10 men and 13 women.

Total earning of 10 men = 10 * (earning of 1 man) = 10 * 55 = 550.

Total earning of 13 women = 13 * (earning of 1 woman) = 13 * 39.29 ≈ 510.77.

Therefore, the total earning of 10 men and 13 women is approximately 550 + 510.77 = 1060.77.

Summary:
- 1 man earns 55 units of currency.
- 1 woman earns approximately 39.29 units of currency.
- Therefore, 10 men and 13 women will earn a total of approximately 1060.77 units of currency.
