Question

Kim is ten years older than babu next year she will be twice as old as him how old they are now

Answer 1

Let the age of babu be x years

Age of kim = x+10 years

In one years, age of kim = x+11

age of babu = x+1

Age of kim is twice that of babu

x+11 = 2(x+1)

x+11=2x+2

x = 9

Present age of  babu = 9 years

Present age of kim = 19 years

Answer 2

Step-by-step explanation:

Let the age of babu be x years

Therefore, age of Kim will be = x + 10 years

After One year

Babu's age = x + 1

Kim's age = x + 11

According to Question,

Age of Kim will be twice that of babu after a year

i.e.,

x + 11 = 2 (x+1)

x + 11 = 2x + 2

x = 9

Therefore, the present ages are-

Age of Kim = x + 10

9 + 10

19 years

Age of babu= x = 9 years

After 10 years-

Age of Kim = x + 11

9 + 11

20 years

Age of babu = x + 1

10 years
