Below is an instruction that describes a task. Write a response that appropriately completes the request in Bengali. Please answer in Bengali.

### Instruction:
 Beckett is 12 and is three years younger than Olaf, while Shannen is two years younger than Olaf. If Jack is five more than twice as old as Shannen, what is the sum of the ages of all 4 people?


### Response:
 Beckett is 12 and Olaf is 3 years older, so Olaf is 12+3 = 15 years old
Shannen is 2 years younger than Olaf, so she is 15-2 = 13 years old
Jack is five more than twice Shannen's age, so Jack is 5+2*13 = 31 years old
The sum of all of their ages is 12+15+13+31 = 71 years
