Question

How much steel sheet was actually used, if 1/12 of the steel was wasted in making the tank.Find

Answer 1

Answer:

11/12

91.67 %

Step-by-step explanation:

Let say Total steel was = 12 S

1/12 of the steel was wasted in making the tank

Wasted Steel = (1/12) 12S

=> Wasted Steel = S

Steel Used in Making Tank  = Total Steel - Steel Wasted

=> Steel Used in Making Tank  =  12 - S = 11S

steel sheet actually used =  11S/12S

= 11/12

steel sheet actually used  in % = 91.67 %

Answer 2

Answer:

$91.67 %$

Step-by-step explanation:

Consider total steel sheet used = $S$

given is $\frac{1}{12}$ of steel was wasted,that is $\frac{1}{12} \times S$ .

therefore, actual steel sheet used $= S-\frac{S}{12} \\= \frac{11S}{12}$

and ,% sheet used $= \frac{11S}{12\times S} \times 100\\= \frac{1100}{12} \\= 91.667 \ percent$
