B) 3 yr
C) 2 yr 6 months
D) 3 yr 1 month
Correct Answer: A
Solution :
Let the age of first brother \[=8x\,yr\] and age of second brother \[=5x\,yr\] According to question, 8x = 4 yr 8 months \[\Rightarrow \] \[8x=4\frac{8}{12}\] \[\Rightarrow \] \[x=\frac{56}{12\times 8}=\frac{7}{12}\] \[\therefore \] Age of younger brother \[=5x=5\times \frac{7}{12}\] \[=\frac{35}{12}=2\frac{11}{12}\] = 2yr 11 monthsYou need to login to perform this action.
