Question

A length of a bacteria enlarged 50,000 times attains a length of
5 cm. What is the actual length of the bacteria? If the length is
enlarged 20,000 times only, what would be its enlarged length?
​

Answer 1

2m will ans. Because make a table of direct proportion and cross multiply and divide it will get 2m

Answer 2

Given:-

• The length of a bacteria when enlarged 50,000 times is 5 cm.

To find:-

• The actual length of the bacteria.
• The length of the bacteria after enlarging 20,000 times

$\small\bf\pink{Let's\:do\:it\:mate\:!}$

Here,

The length of the bacteria when enlarged 50,000 times is 2 cm.

Now,

let the actual size of the bacteria be x

That is,

$\sf{50000x = 5cm}$

$\sf{\implies \: x = \frac{5}{50000} }$

$\sf{\implies \: x = \frac{1}{10000} }$

$\sf{\implies \: x = 10 {}^{ - 4} }$

Hence,

$\bf{The \: actual \: size \: of \: the \: bacteria \: is 10 {}^{ - 4} }$

Now,

let's find the size of the bacteria when enlarged 20,000 times.

That is

$\sf{ \implies \: 10 {}^{ - 4} \times 20000}$

$\sf{\implies\: 2}$

Therefore,

The length of the bacteria when enlarged 20,000 is 2 cm.

Answers:-

$\small\bf{The\: actually\: size\: of \:the\: bacteria \: is \: 10 {}^{ - 4} }$

The length of the bacteria after enlarging 20,000 times is 2 cm.
