Question 10

# The ratio of present ages of L and N is 7 : 5. If the age of N after seven years will be 32 years, then what is the present age (in years) of L?

Solution

Let present ages of L and N be $$7x$$ years and $$5x$$ years respectively.

Thus, N's age after 7 years = $$5x+7=32$$

=> $$5x=32-7=25$$

=> $$x=\frac{25}{5}=5$$

$$\therefore$$ L's age = $$7\times5=35$$ years

=> Ans - (B)
