8. A, B and C can complete a work in 40, 48 and 60 days respectively. They received Rs. 13200 to complete the work. They begin the work together but B left 2 days before the completion of the work, and C left 5 days before the completion of the work. A has completed the remaining work alone. What is the share of B (in Rs.)

⇒ B left 2 days before completion
B's 2 days work → 5 × 2 = 10 units
⇒ C left 5 days before completion
C's 5 days work → 5 × 4 = 20 units .
∴ Now total work = (240 + 10 + 20) units .= 270units
∴Time taken for the work to be completed
= 270 / 6+5+4 = 18 days
Now A worked for 18 days
B worked for 16 days
C worked for 13 days .
∴ Wages will be divided in the ratio
A: B: C = 18×6:16×5:13 × 4
A:B:C = 27:20:13
∴ Share of B = 20/ 27+20+13 × 13200 =Rs. 4400

⇒ B left 2 days before completion
B's 2 days work → 5 × 2 = 10 units
⇒ C left 5 days before completion
C's 5 days work → 5 × 4 = 20 units .
∴ Now total work = (240 + 10 + 20) units .= 270units
∴Time taken for the work to be completed
= 270 / 6+5+4 = 18 days
Now A worked for 18 days
B worked for 16 days
C worked for 13 days .
∴ Wages will be divided in the ratio
A: B: C = 18×6:16×5:13 × 4
A:B:C = 27:20:13
∴ Share of B = 20/ 27+20+13 × 13200 =Rs. 4400

⇒ B left 2 days before completion
B's 2 days work → 5 × 2 = 10 units
⇒ C left 5 days before completion
C's 5 days work → 5 × 4 = 20 units .
∴ Now total work = (240 + 10 + 20) units .= 270units
∴Time taken for the work to be completed
= 270 / 6+5+4 = 18 days
