Answer: 44 years
Step-by-step explanation:
Let Brita's age be x and the daughter's age be y , then from the first statement :

From the second statement :

solving the resulting linear equation , add the two equations , we have


substitute 74 into equation 1 to find the value of y



Therefore :
Eva = 44 years
To solve for time taken we use the compound formula:
A=P(1+r/100*n)^(n*t)
where:
A=future value
P=principle
r=rate
t=time
n=number of terms
6265=4000(1+7.5/(12*100))^(12t)
solving for t we get
1.56625=1.00625^12t
12t=72.0136
t=6.00 years
