### Ex 2.6 Class 8 Maths Question 6.

The ages of Hari and Harry are in the ratio 5 : 7. Four years from now, the ratio of their ages will be 3 : 4. Find their present ages.

Solution.
Let the present ages of Hari and Harry be 5x years and 7x years, respectively.

Present age of Hari = 5 × 4 years = 20 years
Present age of Harry = 7 × 4 years = 28 years.

### Ex 2.6 Class 8 Maths Question 7.

The denominator of a rational number is greater than its numerator by 8. If the numerator is increased by 17 and the denominator is decreased by 1, the number obtained is 3/2. Find the rational number.

Solution.
Let the numerator of the given rational number be x.

Then, the denominator of the rational number = x + 8
The rational number = x/(x + 8)
If the numerator is increased by 17 and the denominator is decreased by 1, the number becomes 3/2.

Hence, the required rational number is 13/21.
