Need the answer of the b <br>brainliest for the best answer​
Westkost [7]

answer

7.24

explanation

40% of 6000 = 2400

6000-2400=3600

labour's cost = 2400

material cost = 3600

15% of 2400 = 360

2400 + 360 = 2760

20% of 3600 = 720

3600 - 720 = 2880

2760 + 2880 = 5560

6000 : 5560 = 92.76

gap = 100.00 - 92.76

= 7.24
