A Correct answer
Explanation

Total ratio = 4+5+7 = 16. B's share = 5/16 * 480 = 5 * 30 = 150 total. Daily income = 150 / 6 = 25.

AI explanation

Since wages for work are distributed using the efficiency ratio, the total pay of Rs. 480 is divided in the ratio 4 : 5 : 7. The total number of efficiency units is 4 + 5 + 7, equaling 16 units, and the value of one unit is Rs. 480 divided by 16, which is Rs. 30. B's total share for the 6 days of work is 5 units multiplied by Rs. 30, resulting in Rs. 150. Dividing this total share by the 6 days worked gives B's daily income of Rs. 25.
