Question

One year ago the ratio of Anil's and Sunil's age was $6:7$. Four years hence their ratio would become $7:8$. How old is Sunil ?

• A. $36$
• B. $26$
• C. $46$
• D. $40$

Answer 1

Answer: (A)

$36$

Let Anil's and Sunil's ages one year ago be $6x$ and $7x$, respectively.

Then their ages $4$ years hence are $(6x+5)$ years and $(7x+5)$ years.
$\Rightarrow \frac{6x+5}{7x+5}=\frac{7}{8}$ or $x=5$
Hence, Sunil's present age $=7x+1=36$ years
