In a factory, 25 men working 26 hours can produce 1 300 radios. How many hours must the same group of men work to produce 450 radios ?

$\large\sf\underline\red{Answer \: :-}$

Given that,

In a factory,

25 men work 26 hours and produce 1300 radios.

We have to find,

If 25 men produce 450 radios then what will take time?

Concept :-

We find first of all how many radios make in 1 hour, then we easily find how many take time to make 450 radios.

Finding how many radios make in 1 hour

$\sf\dashrightarrow{ \frac{1300}{26} = 50 \: radios}$

By cross multiply,

$\sf\dashrightarrow{ \frac{450}{x} = \frac{50}{1} } \\ \\ \sf\dashrightarrow{x = \frac{450}{50} } \: \: \: \\ \\ \sf\dashrightarrow{x = 9 } \: \: \: \: \: \: \: \:$

25 take 9 hours to make 450 radios.
