Question

the bacteria in a culture grows by 5%in the first hour decreases by 8% in the second hour and again increases by 10% in the third hour find the count of bacteria at the end of 3 hours,if its count was 10000​

Answer 1

Answer:

Rs.10626

Step-by-step explanation:

Bacteria at the end of 3 hours

A=p(1+a/100)(1+b/100)(1+c/100)

=10000(1+5/100)(1-8/100)(1+10/100)

=10000×105/100×92/100×110/100

A=Rs.10626

Answer 2

Answer:

Rs.10626

Step-by-step explanation:

Given : he bacteria in a culture grows by 5%in the first hour decreases by 8% in the second hour and again increases by 10% in the third hour

To solve : find the count of bacteria at the end of 3 hours,if its count was 10000​

Solution :

Bacteria at the end of 3 hours

A = p ( 1 + a / 1 0 0 ) ( 1 + b / 1 0 0 ) ( 1 + c / 1 0 0 )

= 1 0 0 0 0 ( 1 + 5 / 1 0 0 ) ( 1 - 8 / 1 0 0 ) ( 1 + 1 0 / 1 0 0 )

=1 0 0 0 0 × 1 0 5 / 1 0 0 × 9 2 /  1 0 0 0 × 1 1 0 / 1 0 0

A = R s . 1 0 6 2 6
