Answer 1

Answer:

more 27

Step-by-step explanation:

because 27 men in half completed 1/5 work

Answer 2

There are 81 more men needed to finish the work in time. and Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Number of worksmen = 37

Number of days = 42

In 21 days, only $\dfrac{1}{5}$ work is done.

Remaining work = $1-\dfrac{1}{5}=\dfrac{5-1}{5}=\dfrac{4}{5}$

So, we will use "time and work":

According to question, it becomes,

$\dfrac{27\times 21}{\dfrac{1}{5}}=\dfrac{x\times 21}{\dfrac{4}{5}}\\\\27\times 4=x\\\\x=108$

So, Number of more men is given by

108 - 27 = 81

Hence, there are 81 more men needed to finish the work in time. and Option 'c' is correct.
