Answer» Daughter's AGE is 16 and mother's is 40Step-by-step explanation:let's assume that the present age of the mother is x and daughter's is ystep 1sum of their present age is 56Equation 1 : x+y = 56Equation 2 : x= (56-y)4 years ago their age RATIO is 3:1step 2Equation 3 : [(x-4)/[(y-4)] = [3/1]from Equation 1 and 2 we can write Equation 3 as by putting the value x= (56-y) we get[(56-y) - 4= 3 ( y -4)52 -y = 3Y -1264 = 4yy = 16And by putting value y in Equation 2 we get x = (56-y) x = 40We can say that the present age of daughter's is 16 and mother's is 40 |
