Question

riyaz mother is seven times older than him. four years from now, she will be four times as old as riyaz will then be. what are their present ages

Answer 1

let riyaz age b x
mothers age=7x
4 yrs later:
riyaz age=x+4
mother age=7x+4
a/q
7x+4=4(x+4)
7x+4=4x+16
7x-4x=16-4
3x=12
x=4
therefore, riyaz age=4
mothers age=7(4)=28

Answer 2

Answer:

riyaz's Age = x

his mother's age = 7x

after 4 years,

riyaz's age will be = x + 4

his mother's age = 7x + 4 or 4x +4

therefore a/q,

7x+4=4(x+4)

7x+4=4x+16

7x-4x=16-4

3x = 12

x = 12/3

x = 4

then,

4*7+4

28+4

32
