Question

Rahim's and his wife's age are in the ratio 4: 3. After 4 years the ratio of their age will be 9:7. Then the required equation is

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

Let the present age of Rahim be $4x$ years
So, present age of Rahim’s wife is $3x$ years
Rahim's age after 4 years = $4x+4$ years and his wife’s age will be $3x+4$
After 4 years , the ratio of their ages is 9:7
$\therefore \frac{4x+4}{3x+4}=\frac{9}{7}$
