Question

20). A photograph of a bacteria
enlarged 50000 times attains a
length of 5 cm. The actual length of
bacteria is
O
1000 cm
O 1/1000 cm
O 1/10000 cm
O 1/100 cm​

Answer 1

1/10000
5/50000
0.0001 so into fraction 1/10000

Answer 2

Answer:

1/10000 cm

Step-by-step explanation:

Let the actual length of bacteria be x cm

No. of times photo enlarged = 1 50000

Length of bacteria (in cm) = x 5

As more Enlarged, the length of bacteria will more increase.

So, it is the case of direct proportion.

Since, 1/x = 50000/5

x = 5/50000

x = 1/10000

Hence, the actual length of the bacteria is 1/10000 cm
