Question

Anita can do a work in 30 days sunita is 20% more efficient than anita. The number of days taken by sunita to do the same work is

Answer 1

Answer:

25 Days

Step-by-step explanation:

Anita's 1 day work = 1/30

Sunita 's 1 day work = 1/30 ( 1 + 20/100) = 1.2/30

Number of days taken by sunita = 1 / (1.2/30)

= 30/1.2

= 25

Answer 2

The number of days taken by sunita to do the same work is 25

Solution:

sunita is 20% more efficient than anita

Ratio of times taken by Anitha and Sunitha is:

120 : 100

Reduce to lowest terms

6 : 5

Anita can do a work in 30 days

Suppose Sunitha takes x days to do the work

Therefore,

6 : 5 : : 30 : x

Then,

$6 \times x = 5 \times 30\\\\x = 5 \times 5\\\\x = 25$

Thus, number of days taken by sunita to do the same work is 25 days
