Question

In four years Cranston’s age will be the same as Terrill’s age is now. In two years time, Terrill will be twice as old as Cranston. Find their ages now.

Answer 1

Answer:

Cranston's Age: 2 years

Terril's Age: 6 years

Step-by-step explanation:

c = Cranston

t = Terril

Information we have:

c + 4 = t

t + 2 = 2c

So, if Cranston is 2 and Terril is 6, it's true as c + 4 (2 + 4) is 6 and When Cranston and Terril age 2 years, Cranston will be 4 and Terril will be 8, so Terril will be twice of Cranston's age.

*A lot of people forget the part where Cranston will ALSO age, so they get t = 10 and c = 6

Answer 2

Uuuuh...
 c + 4 = t 
t + 2 = 2c 
c + 4 = 2c – 2 
c = 2 
t = 6


or

c = t - 4....................................(1) 

in 2 years we have: 

t + 2 = 2(c + 2) 

i.........e......... t + 2 = 2c + 4 

=> t - 2c = 2...........................(2) 

(1) into (2) for c gives: 

t - 2(t - 4) = 2 

i.........e......... 8 - t = 2 

so, t = 6 and c = 2 

therefore, terrill is 6 and cranston is 2 

and, in 2 years time they shall be 8 and 4....................................i..... terrill being twice cranston's age 

i lost myself the first time i solved it
