Show Answer
Answer:
Correct Answer: A
Solution:
- Let the present ages of Manoj and Wasim be 3x yr and 11x yr, respectively.
According to the question,
$ 11x=85-7-12 $
$ \Rightarrow $ $ 11x=66 $
$ \therefore $ $ x=6 $
$ \therefore $ Present age of Manoj $ =3\times 6=18yr $
Hence, present age of Manoj’s father
$ =18+25=43yr $
