Question

Apurva can do a piece of work in 12 days Apurva and Amit complete the work together and were paid rupees 54 and 81 respectively how many days must be have taken to complete the work together​

Answer 1

Answer:

Let X be the no. of days Amit taken

I/12:1/x = 54:81

I/ Xx54 =81x1/i2

54/x = 81/12

x = 8

I/12 +1/8= (3+2)/36 = 5/36,

36,/5=7 I/5 days

They take 7 1/5 days to complete

Answer 2

They must take 4.8 days.

Step-by-step explanation:

Consider the provided information.

Apurva and Amit complete the work together and were paid rupees 54 and 81 respectively.

Therefore, $\frac{Apurva }{Amit } =\frac{54}{81}=\frac{2}{3}$

The ratio of money given to Apurva and Amit is 2:3.

That means their work time ratio would be 3:2.

Apurva takes 12 days, Amit  would take 8 days and the total number of days required (t) would be given by the equation:

$(\frac{1}{12}+\frac{1}{8})t = 1$

$(\frac{2+3}{24})t = 1$

$\frac{5t}{24} = 1$

$5t = 24$

$t=4.8$

Hence, they must take 4.8 days.
