| The ratio of the present age of Manoj to that of Wasim is 3: 11. Wasim is 12 yr younger than Rehana. Rehana's age after 7 yr will be 85 yr. What is the present age of Manoj's father, who is 25 yr older than Manoj? |
A) 43 yr
B) 67 yr
C) 46 yr
D) 69 yr
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 \[=3\times 6=18\,\,yr\] |
| Hence, present age of Manoj's father |
| \[=18+25=43\,\,yr\] |
