Eight workers paint a house in 6 days. How long does it take for 3 workers to paint the same house?
Answers
Answer:
Ans :- They take 16 days.
Step-by-step explanation:
Because
(8) 6 = (2) X2
X2 = 8 x 6/3
= X2 = 48/3 = 16.
Answer:
steps :
1. 8 workers → 6 days → 1 house
2. 8 worker ÷8 → 6 days x 8( Inverse proportionality ) → 1 house = 1 worker → 48 days → 1 house
3. 1 worker x 3 → 48 days ÷ 3( Inverse proportionality) → 1 house
= 3 WORKERS → 16 DAYS → 1 HOUSE ( ANSWER)
Step-by-step explanation:
Hi. Pls understand that in this question logic is the key. We need to understand that in real life application if number of people increase the number of days to do the work decrease because the work is being done at a faster rate. So, you can observe that this shows inverse proportionality. If no. of workers increase. No. of days to complete the work decrease. So, if you are dividing the whole equation by 3 to find the rate of 1 worker you should multiply 3 for the number of days. BUT the no. of houses painted remains the same. Because we are only looking at No. of workers and no. of days to paint. BUT remember whenever we change the no. of workers or the no.of days we NEVER change the no. of house. Because we r only looking at no.of days and no.of workers. Hope this helps !!!
