Answer 2

Answer:

2 cms

Step-by-step explanation:

• the bacteria is enlarged 50,000 times and attains 5 cm length
• and as per same bacteria if it enlarged 20,000 times the answer is going to be

50,000-5

20,000-?

which we can also write as

50,000:5 :: 20,000:?

now we see the means and extreams and

we know the product of means is product of extreams so

5x20000=50000xX

1,00,000=50000xX

X=100000 =2

50000

hence the answer is solved
