Given :-
- 12 workers can do a piece of work in 20 days .
To Find :-
- How many workers should be added to complete the work in 16 days ?
Solution :-
According to the question ,
→ In 20days 12 workers can do a piece of work.
→ In 1day 12*20 workers can do that work
( Less days , more workers )
→ In 16 days 12*20/16 = 15 workers can do the work.
So 15 -12 = 3 workers should be added to complete the work.
<u>Hence</u><u> the</u><u> required</u><u> answer</u><u> is</u><u> </u><u>3 </u><u>.</u>

3x+2y=11
y=5x-1
Substitute the y in the first equation:
3x+2(5x-1)=11
y=5x-1
3x+10x-2=11
y=5x-1
13x=13
y=5x-1
Now substitute the x to find the y:
x=1
y=5-1=4
100x5=500
90x5= 450
8x5= 40now add
500+450+40=990
:) hope this helps
Use the formula for the volume of a cylinder.
V = area of the base * height
area of the base = π (radius)^2
V = π(radius)^2 * height = π(8 in)^2 (18in) = 1,152π in^3
If you use π≈3.14, you get
V = 3,617.28 in^3
