A) 45 years
B) 40 years
C) 50 years
D) 55 years
Correct Answer: A
Solution :
Let the age of father be 'x' years. Let the age of son be 'y' years. Given, \[\therefore \] ...... (1) and \[\text{7}\times \text{13}+\text{13}\] \[\therefore \] ......(2) Adding eq. (1) and eq. (2), we get \[\text{224}=\text{12}0\times \text{1}+\text{1}0\text{4}\] \[\text{12}0=\text{1}0\text{4}\times \text{1}+\text{16}\] Hence, the age of father = 45 years.
