First and best => Brainliest

Answer 1

The cow produces calf every year .

After one year

The cow produced one calf .

Hence number of cows = 1 + 1 = 2

After two years

The cow produced another calf

Number of cows = 2 + 1 = 3

After three years

Another calf is produced.

Number of cows = 3 + 1 = 4

After four years.

In the fourth year the first born cow can produce a cow.

Hence 2 cows are produced in this year.

Number of cows = 4 + 2 = 6

After five years.

In the fifth year the second cow can produce another baby.

Hence 3 will be produced .

This sequence will follow upto 8 years

So : 6 + 3 + 4 + 5 will be the number of cows after 7 years.

= 9 + 4 + 5

= 13 + 5

= 18

Hence 18 cows will be there at the beginning of the 8 th year.

This was a nice question . Thank you !

After three years

Another calf is produced.

Number of cows = 3 + 1 = 4


After four years.

In the fourth year the first born cow can produce a cow.

Hence 2 cows are produced in this year.

Number of cows = 4 + 2 = 6


After five years.

= 13 + 5

= 18

Hence 18 cows will be there at the beginning of the 8 th year.
