Anil is 9 years older than Ajith. in 10 years, Anil will be twice as old as Ajith was 10 years ago. Find their present ages.

Sagot :

PRESENT AGES;
Ajith: x
Anil: x + 9

AGE 10 YEARS AGO of AJITH:
x - 10

AGE IN 10 YEARS (FUTURE) OF ANIL:
Present age (x + 9) + 10 = x + 19

Equation:
In 10 years, Anil will be twice as old as Ajith 10 years ago:
x + 19 = 2 ( x - 10)

x + 19 = 2x - 20

2x - x = 19 + 20

x = 39,  

THEIR PRESENT AGES:

AJITH: x = 39 years old

ANIL:  X + 9 = 39 + 9 = 48 years old
