Question

At present, Ami's age is twice
Dio's age and Cami is two
years older than Ami. Two
years ago, the respective ratio
between Rio's age at that time
and Cami's age at that time
was 4:9. What will be Ami's
age four years hence?
MT 40 years (2) 30 years
(3) 42 years (4) 36 years
(5) 48 years​

Answer 1

answer 40

Step-by-step explanation:

present age of AMI= x

present age of dio = x\ 2

present age of cami = x+2

2 years ago

dio present age = -2

cami present age= - 2 = 4 /9

x /2 -2 = 4/9

(x - 4 ) 9 = 4 ×2x

9x - 36 = 8x

so

x = 36

age of ami after 4 years

present age of ami (+ 4)

36 + 4

40
