Question

State if True or False

The monthly income and the monthly expenditure of a man are Rs. 15,000 and Rs. 10,500. The ratio between his monthly expenditure to savings is 7:3. Also find the sum of the numerator and denominator of the ratio in its lowest form.

Answer 1

Monthly savings of the man is $Rs15000-Rs10500=Rs4500$
Ratio of monthly expenditure and savings of the man are $=Rs10500:Rs4500$

Simplifying it by dividing by $100$, we get the ratio $=105:45$

Further simplifying, by dividing by $15$, we get the ratio $=7:3$

Thus the sum of the nummerator and denominator in their lowest form is $7+3=10$.
