b) The sum of Pintu’s and Chintu’s age 2 years from now.

Answer 1

Answer: let the chintu's age be x then x+5

and pintu's age be y

so,

y=3x

a) y=3x+5

b) [pintu's age +chintu's age]after 2 years

  [3x+x]2

Answer 2

Pintu’s age 5 years from now = 3x + 5  Years & The sum of Pintu’s and Chintu’s age 2 years from now = 4x + 4

Step-by-step explanation:

Chintu is x years old

Pintu is 3 times as old as Chintu

=> Pintu age = 3x   Years

Pintu’s age 5 years from now = 3x + 5  Years

Chintu is 5 years older than Jimmy.

=> Jimmy age  = x - 5

Pintu’s age 2 years from now = 3x + 2  Years

Chintu’s age 2 years from now = x + 2  Years

The sum of Pintu’s and Chintu’s age 2 years from now.

= 3x + 2 + x + 2

= 4x + 4

The sum of Pintu’s and Chintu’s age 2 years from now = 4x + 4
