A) 50 years, 25 years, 20 years
B) 40 years, 20 years, 15 years
C) 20 years, 15 years, 10 years
D) 25 years, 20 years, 10 years
Correct Answer: D
Solution :
Let the present ages of A, B, C and D are \[x,y,z\]and t respectively. Since, present age of D = t = 48 years. According to question, \[x=y+5\] ?(i) \[z=\frac{1}{2}y\] ?(ii) \[t=2y+8\] ?(iii) From (iii), \[48=2y+8\] \[\Rightarrow \] \[2y=40\Rightarrow y=20\]years From (ii), \[x=\frac{1}{2}\times 20=10\]years From (i), \[x=20+5=25\]years So, present ages of A, B and C are 25 year, 20, years and 10 years respectively.You need to login to perform this action.
