A) 4 : 3
B) 5 : 3
C) 3 : 5
D) 10 : 7
Correct Answer: B
Solution :
Let Present age of father = x year and present age of Son \[=\left( 100-x \right)\]years Then, 5 years ago, \[\frac{x}{(100-x)-5}=\frac{2}{1}\] \[x-5=190-2x\] \[3x=195\] \[x=65\] Hence, After 10 years \[\frac{Father's\,\,age}{Son's\,\,age}=\frac{65+10}{(100-65)+10}\] \[=\frac{75}{45}=\frac{5}{3}\]You need to login to perform this action.
