Step-by-step explanation:

Jaise ke pass bahut din hai isliye uski madad Karega ki

Answer 2

${\huge{\overbrace{\underbrace{\red{SoluTion}}}}}$

No. of days taken by a to complete the work alone = 8

No. of days taken by b to complete the work alone = 12

∵ a, b and c finish the work in 4 days

∴ a + b + c = 4

$\boxed {\mathrm {L.C.M=24}}$

Efficiency :-

a = 3

b = 2

a + b + c = 6

c = 6-2-3

c = 1

Now,

$\sf {\mapsto \ a : b : c = 3 : 2 : 1 = 6}\\\\\\\sf {\Rightarrow \ \frac{1}{6} \times 4500}\\\\\\\sf {\Rightarrow \ \frac{4500}{6} }\\\\\\\sf {\Rightarrow} \ \boxed { \rm 750\ rupees}$

Share of c = 750 rupees
