Furnell is 5 years older than Juana. In 5 years the sum of their ages will be 71. How old is Furnell now?

Answer 1

F=J+5

F+5 + J+5 = 71

F+5 + F = 71

2F = 66

F = 33 years old = Furnell's age now

J = 33-5 = 28 years old = Juana's age now

F is now 33 years old

in 5 years they'll be 38 and 33

38+33 = 71
