The ratio of the income to the expenditure of a family is $$7 : 6$$. Find the savings if the income is Rs. $$1400$$.
Correct option is A. Rs. $$200$$.
Given,
Income of a family $$ = Rs.1400$$
The ratio of the income to the expenditure of the family $$= 7:6$$.
Let,
Expenditure of the family $$ =6x$$
The income of the family $$= 7x$$
$$1400 = 7x$$
$$x = Rs. 200$$
We know that,
Savings of a family = income of the family - expenditure of the family.
= $$x$$
$$\therefore$$ savings of the family is $$ Rs. 200$$
