Question

Jacob is 6 years older than john in 4 years time their sum. of the ages will be 30 years find their present ages. ​

Answer 1

Answer:

Jacob is 10 years

John is 4 yrs old.

Step-by-step explanation:

let age of john be x,

then, Jacob's age = x + 6

After 4 years ,

John age = x + 4

jacob age = 4+(x+6) = x +10

sum of their ages = x+4 + x + 10 = 2x + 14

But, sum of their ages after 4 yrs = 30 ( according to the question)

→ 2x+14=30

→x=(30-14)/2= 16/2 = 4

Hence, John age = 4 yrs

& Jacob age = x+6= 4+6=10yrs
