Question

35 workers built house in 160 days how many days will 28 workers take to build the same house working at the same rate​

Answer 1

35 workers can built house in=160 days

Then 1 man=35×160 days

Less Man More Days

If One man take 35×160 days

Then 28 men=35×160/28

As 1 man can do Work in 35×160 days when there is 28 men days take will be less so,Divide 35×160 in 28 men

$\mathbf{\frac{35 \times \cancel{160}}{ \cancel{28}} } \\ \\ \mathbf{ \frac{ \cancel{35} \times 40}{ \cancel7} } \\ \\ \implies\mathbf{ 5 \times 40} \\ \\ \implies200 \: days$

$\boxed{\mathbf{\huge{Days=200}}}$

Answer 2

Hey There.....!!

Given-:

35 workers take 160 days

1 worker will take =

(160 * 35)days

{More People Less Days And Less People More Days}

So, 28 workers will take

= (160*35)/28

=(35*40)/7

= 5*40

= 200 daYß

Hence 28 workers will take 200 daYß

Hope this helps!!!❤
