A) 35
B) 10
C) 20
D) 15
Correct Answer: D
Solution :
Let the age of Renu = x yr. and age Renu?s mother = y yr According to the question, \[(y-5)=3x(x-5)\] \[\Rightarrow \] \[y-5=3x-15\] \[\Rightarrow \] \[y-3x=-10\] ?(i) and \[(y-5)=2(x+5)\] \[\Rightarrow \] \[\,y+5=2x+10\] \[\Rightarrow \] \[y-2x=5\] ?(ii) On solving Eqs. (i) and (ii), we get x = 15, y = 15yr \[\therefore \] Renu?s present age = 15 yrYou need to login to perform this action.
