Option 1: Rs. 210
Option 2: Rs. 100
Option 3: Rs. 200
Option 4: Rs. 475
Correct Answer: Rs. 100
Solution :
Given: A, B, and C are employed to do a piece of work for Rs. 575.
Let the total work be 23 units.
So, A and C completed 19 units together.
⇒ (23 – 19) = 4 units are completed by B
So, amount paid to B = $\frac{4}{23}×575$ = Rs. 100
Hence, the correct answer is Rs. 100.
