Explanation:

- The ratio of the daily wages of men to women is given as 4:3.

- Let the daily wage of a man be 4x and that of a woman be 3x.

- The total earnings for 15 men and 25 women is Rs 5,400.

- Therefore, the equation is: 15(4x) + 25(3x) = 5,400.

- Simplifying: 60x + 75x = 5,400.

- Combined, this gives: 135x = 5,400.

- Solving for x, we find: x = 40.

- Therefore, a man's daily wage is 4x = Rs 160 and a woman's is 3x = Rs 120.

- The total wages for 1 man (Rs 160) and 5 women (5 x Rs 120) is Rs 760.

- Option 4: Rs 760 is correct.
