Q) A and B enter into a partnership with Rs 50000 and Rs 60000 .C joins them after x months contributing Rs 70000 and B leaves x months before the end of the year .If they share ratio of 20:18:21 then find the valuer of x?

We calculating the ratio for 12 months
A's contribution= 50000*12
since B left x months before the end of the year so his contribution=60000(12x)
and same for C= 70000(12x)
their ratios
50000*12:60000(12x):70000(12x)
=> 60 : 6(12x) : 7(12x)
Now given ratio is 20:18:21
so we divide by 3 in the ratio
=> 20 : 3(12x) : 7(12x)/3
on comparing the B's ratio with the given one we get
3(12x)=18
x=3
