Answer 1

Answer:

32 men took 15 days

1men took 32×15

20 men took (32×15)/20

i.e 24 days

Answer 2

Answer:

24 days will take to do same work of school

Given:-

• it take 32 men in 15 days to build a wood work shop for a school

To find:-

• how many days can 20 men build the same work

Solution:-

Let the time taken to build the wood workshop

be X days

Hence,

More taps will take less time to build work shop

hence this is inverse variation.

men 32 20

days 15 x

$32 \times 15 = 20 \times x \\ \\ x = \frac{32 \times 15}{20} \\ \\ x = 24$

24 days will take to do same work of school
