Question

dinu and raghu can plough a field in 15 days . if dinu alone can plough 1/8 of the field in 5 days , how many days will raghu take to do the same job?

Answer 1

Let work of raghu = 1/x
Then, according to the question ;

Dinu & raghu together plough the = 15 days
From the question :-
Dinu plough alone = 1/8 of the field in 5 days
Now,
Work done by Dinu
1/8 = 5 = 40 days
Therefore ,
Dinu work/day = 1/40
As per question :-
Dinu & Raghu work together ;
1/40 + 1/x = 1/15
X+40/40x = 1/15
15x + 600 = 40x
25x = 600
x =24
So, Raghu take 24 days to do the same job.
