Question

The sum of the ages of jamil and tallal is 70 years . In 10 years jamil will be twice as old as talkative . find their present ages ?​

Answer 1

Answer:

jamil age = 50,

tallal age = 20

Step-by-step explanation:

let age of jamil  be = x

let age of tallal be = y

sum of age = x+y = 70 (eq -1)

in 10 years jamil will be twice as old as talkative =

x+10 =  2(y+10)

x+10 = 2y + 20

x= 2y +20-10

x = 2y + 10

putting value  of x in equation 1,

2y+y+10 = 70

3y= 70 - 10

y = 60/3

y = 20

we know ,

20+x = 70

x = 70 -20

x = 50
