If A can do 1 /4 of a work in 3 days and B can do 1 /6 of the same work in 4 days , how much will A get if both work together and are paid Tk. 180 in all ?
- A. Tk. 60
- B. Tk. 60
- C. Tk. 60
- D. Tk. 60
Answer: Option B
Explanation:
A 3 days = 1/4 of a work
:. 1 day = 1/12
B 4 days = 1/6 of a work
:. 1 day = 1/24
In terms of ration
A :B
2x : x = 180
120 : 60
A will get = Tk. 120
:. 1 day = 1/12
B 4 days = 1/6 of a work
:. 1 day = 1/24
In terms of ration
A :B
2x : x = 180
120 : 60
A will get = Tk. 120
