Question

five person paint a house in 3 days when they work 8 hours everyday .then if one person work 4 hours everyday.how much time will he take to compkete the same work?​

Answer 1

Step-by-step explanation:

No. of people required =5

Time taken per day =8 hours

No. of days taken = 3

Total time taken = (8*3)hours

= 24 hours

No. of hours=4

Time required =(24/4) days

=6 days.

Answer 2

He will take 3 days to complete work.

Step-by-step explanation:

5 persons paint 1 house in 3 days in hours = 8

Let $M_1$ be the no. of painters , $D_1$ be the no. of days , $H_1$ be the  no. of hours

$M_1=5\\D_1=3\\H_1=8$

We are supposed to find one person work 4 hours everyday.how much time will he take to complete the same work

Let M_2 be the no. of painters , $D_2$ be the no. of days , $H_2$be the  no. of hours in case 2

$M_2=1\\D_2=?\\H_2=4$

So,$M_1 \times D_1 \times H_1 =M_2 \times D_2 \times H_2\\5 \times 3 \times 8 = 1 \times ? \times 4 \\\frac{5 \times 3 \times 8}{1 \times 4}=?\\30=?$

Hence He will take 3 days to complete work.
