Vedclass · Answer

(A) Let the sum of the ages of the mother,father,and two daughters two years ago be $S_{-2} = 40$ years.There are $4$ people in total.To find the sum of their ages today (present age),we add $2$ years for each of the $4$ people:$S_{present} = 40 + (4 	imes 2) = 40 + 8 = 48$ years.To find the sum of their ages after $3$ years from now,we add $3$ years for each of the $4$ people:$S_{+3} = 48 + (4 	imes 3) = 48 + 12 = 60$ years.Therefore,the sum of their ages after three years will be $60$ years.

Two years ago,the sum of the ages of a mother,father,and two daughters was $40$ years. After three years,what will be the sum of their ages?
