Question

if three men or 6 boys can finish a work in 20 days how long will 4 men and 12 boys take to finish the same work

Answer 1

$\textbf {Hey there, here is the solution.}$

.............................................................................................

STEP 1: Find the ratio:

3 men = 6 boys (Given)

Divide by 3:

1 man = 2 boys
-------------- [ equation 1]

.............................................................................................

STEP 2: Rephrase the question:

Question = 4 men + 12 boys

Substituting [ 1 ] into it:

Question = 4 (2 boys) + 12 boys = 8 + 12 = 20 boys

.............................................................................................

STEP 3: Solve the question:

6 boys = 20 days

1 boy = 20 x 6 = 120 days

20 boys = 120 ÷ 20 = 6 days

.............................................................................................

Answer: 4 men and 12 boys will take 6 days to finish the work

12 boys=12/3=4men

12 boys complete the work in =4*3=12days
