In a equation of maths paper there is a printing mistake,
division (/) sign replaced by multiply (*) sign then what will be the ratio of equation without this mistake and with this mistake.

The printed equation is => (x+y-z)*x

OPtion

1) 1/2x
2) 2x+3y-z/z
3) 1/(x*x)
4) 2x/2x+y-z
5) x/1
6) (x+z)/x
7) x+z/x
8) x+y-z/x*x
9) 1/x
10) 1/(x+y-z)^2

Solution

Printed equation is => (x+y-z)*x
correct equation will be => (x+y-z)/x

ratio will be (x+y-z)/x / (x+y-z)*x
1/x*x

Correct Option: 3 Best Solution (13)

SUDESHNA SEN   14 years AGO

Equation without mistake= (x+y-z)/x
Equation with mistake= (x+y-z)*x
So the ration is= {(x+y-z)/x}/{(x+y-z)*x}
=1/(x*x)..... Option 3)

BECAUSE (x + y - z)/x/((x + y - z) x)
Cancel all the variables, and you will get that because 2:1 = 2/1
Similarly, (x + y -z)/x/((x+y-z) x)
