Question

Roberts father is 4 times as old as Robert . After 5 years,father will be three times as old as Robert .Find their present ages

Answer 1

Answer:

Father's age=40 and Robert's age=10

Step-by-step explanation:

Father = F and Robert =R

given that

F=4*R...........(1)  and

F+5 = 3(R+5)......(2)

Putting equation 1 in equation 2

4R +5 = 3R+15

R= 10

now, put R=10 in equation 1, we get

F=40
