A) 3yr
B) 4yr
C) 5yr
D) 2yr
Correct Answer: B
Solution :
Sol. [b] Let the present age of Beena is x yr. \[\therefore \]Beena's age at the time other marriage = (x - 8) yr \[\therefore \,\,\,\,\,x=1\frac{1}{4}\,of\,(x-8)\,\Rightarrow x=\,\frac{5}{4}\,(x-8)\] \[\Rightarrow \,4x=\,5x\,-\,40\] \[\therefore \,\,x=40yr\] Now Beena's daughter's age\[=\,\frac{1}{10}\,\times \,40\,=\,4yr\]You need to login to perform this action.
