error (Question: 201477.0 )

different question was there in the test

Question:

Varun alone can do a piece of work in 16 hours while Akash alone can do it in 18 hours. They together took Rs. 360 to do the same work. If with the help of Arun, they finish the piece of work in 4 hour, then how much money is paid to Arun?

Options:
A) Rs. 170
B) Rs. 180
C) Rs. 190
D) Rs. 200
Solution:
Ans: (c)



Alt sol:


Varun's work for 4 hr. = 4 × 1/16 = 1/4 part


Varun gets 1/4 × 360 = Rs 90


Akash's work for 4hr. = 4 × 1/18 = 2/9 part


Akash gets = 2/9 × 360 = Rs 80


So, Arun gets = 360 – (90 + 80) = Rs 190
