Solution
The correct option is D 22080
The number of fish at present in the pond = 345
Number of fish after one month = 2 x 345
Number of fish after two months = 2 x 2 x 345
And so on
Number of fish after six months = (2 x 2 x 2 x 2 x 2 x 2) x 345 = 64 x 345
So, number of fish after six months = 22080
The number of fish at present in the pond = 345
Number of fish after one month = 2 x 345
Number of fish after two months = 2 x 2 x 345
And so on
Number of fish after six months = (2 x 2 x 2 x 2 x 2 x 2) x 345 = 64 x 345So, number of fish after six months = 22080
