Solution:
Let the work to be done be "W".
Let's assume that 1 man does "m" amount of work in 1 day, and 1 boy does "b" amount of work in 1 day.
From the given information, we can form the following equations:
Equation 1: 2m x 14 + 7b x 14 = W
Equation 2: 3m x 11 + 8b x 11 = W
Solving the above two equations, we get:
m = W/154 and b = W/308
Now, we need to find the number of days required for 8 men and 6 boys to do three times the amount of work W.
Let's assume that "d" number of days are required for 8 men and 6 boys to do three times the amount of work W.
From the given information, we can form the following equation:
Equation 3: 8m x d + 6b x d = 3W
Substituting the values of "m" and "b" in Equation 3, we get:
8(W/154) x d + 6(W/308) x d = 3W
Simplifying the above equation, we get:
d = 33
Hence, 8 men and 6 boys can do three times the amount of work W in 33 days.
Answer: 8 men and 6 boys can do three times the amount of work in 33 days.
Let the work to be done be "W".
Let's assume that 1 man does "m" amount of work in 1 day, and 1 boy does "b" amount of work in 1 day.
From the given information, we can form the following equations:
Equation 1: 2m x 14 + 7b x 14 = W
Equation 2: 3m x 11 + 8b x 11 = W
Solving the above two equations, we get:
m = W/154 and b = W/308
Now, we need to find the number of days required for 8 men and 6 boys to do three times the amount of work W.
Let's assume that "d" number of days are required for 8 men and 6 boys to do three times the amount of work W.
From the given information, we can form the following equation:
Equation 3: 8m x d + 6b x d = 3W
Substituting the values of "m" and "b" in Equation 3, we get:
8(W/154) x d + 6(W/308) x d = 3W
Simplifying the above equation, we get:
d = 33
Hence, 8 men and 6 boys can do three times the amount of work W in 33 days.
Answer: 8 men and 6 boys can do three times the amount of work in 33 days.
