A) After 2 months
B) After 3 months
C) After 4 months
D) After 5 months
Correct Answer: B
Solution :
Let Q join for x months. \[\therefore \]Ratio of capital \[=2525\times 12:1200\times x\] \[=2525:100x=101:4x\] \[\therefore \] P?s profit \[=\frac{101}{101+4x}\times 1644\] \[\Rightarrow \] \[1212=\frac{101\times 1644}{101+4x}\] \[\Rightarrow \] \[\frac{1}{137}=\frac{1}{101+4x}\] \[\Rightarrow \] \[4x=36\] \[\therefore \] \[x=9\] Hence, Q joined for 9 months i.e., he joined after 3 months.You need to login to perform this action.
