- Mira’s expenditure and sayings are in the ratio 3: 2.
Question 1:
Mira’s expenditure and sayings are in the ratio 3: 2. Her income increases by 10 percent. Her expenditure also increases by 12 percent. By how much per cent does her saving increase? A. 2%
B. 7%
Feedback We get two values of x ,7 and 13.
But to get a viable answer we must keep in mind that the central value(10)must lie between x and 12.
Thus the value of x should be 7 and not 13
Thus, Required % increase = 7%
