Question

If 5 spiders can catch five flies in five minutes, how many flies can hundred spiders catch in 100 minutes​

Answer 1

Solution :-

Given : 5 spiders can catch five flies in five minutes.

Here,

5 spiders = 5 flies = 5 minutes

1 spider = 1 fly = 5 minutes

Therefore,

100 spiders = 100 flies = 5 minutes

100 spiders = 100 × 2 flies = 5 × 2 minutes

∴ 100 spiders = 100 × 20 flies = 5 × 20 minutes

= 100 spiders = 2000 flies = 100 minutes

Hence,

2000 flies can hundred spiders catch in 100 minutes.

Answer 2

» Five spiders can catch five flies in five minutes.

Then, one spider can caught one fly in five minutes.

But as said in question five spiders can catch five flies in five minutes.

Similarly six spiders caught six flies in five minutes and so on.

But we have to find the number of flies caught by hundred spiders in five minutes.

=> 5 spiders take 5 minutes to caught 5 spiders.

Then the time taken by one spider is $\dfrac{1}{5}$

Hundred spiders caught flies = $\dfrac{1}{5}$ × 100

=> 20

So, in 100 minutes = 20 × 100 = 2000
