3). Rs. 750
4). Rs. 375
This Question has 1 answers.
Given,
A = 8 days, B = 12 days
⇒ A + B + C = 4
LCM of A, B and A + B + C = 24
Efficiency of A, B, (A + B + C) =
= 3, 2, 6
⇒ A + B + C = 6
⇒ C = 6 – 3 – 2 = 1
Ratio of efficiency of A, B, C = 3 : 2 : 1
Total amount = 4500
∴ C's share = 4500 × 1/6 = Rs.750Similar Questions
