Answer:
24 years
Step-by-step explanation:
let the present age be 3x & 4x
so after 16 years ,
3x + 16
&
4x + 16
whose ratio is given as 5 : 6
cross multilingual we get ,
(3x+16)6 = 5(4x+16)
18x + 96 = 20x + 80
16 = 2x
x = 8
so the present age will be 3 × 8 = 24 years

Answer:
A=24 & B =32.
after 16 year
A=40 & B=48
Step-by-step explanation:
Let
A = 3x & B =4x. (from ratio)
after 16 year
A=
3x +16 =5x. &
B =
4x +16 =6x
therefore
A =
16 =5x-3x
2x=16
x= 16/2
x = 8
A=3x
=3 x 8
= 24
after 16 year
A=5x
=5 x 8
=40
B=
4x+16=6x
16 =6x-4x
16=2x
x=16/2
x=8
B=
=4x
=4 x 8
=32
after 16 year
B=6x
=6 x 8
=48
