Statement I : If `| z |

Statement - I : If z = barz then z is purely imaginary Statement- II : If z = -barz then z is purely real

Statement I: If |z_1+z_2|=|z_1|+|z_2|, then Im(z_1/z_2)=0 (z_1,z_2 !=0) Statement II: If |z_1+z_2|=|z_1|+|z_2| then origin, z_1, z_2 are collinear with 'z_1' and z_2 lies on the same side of the origin (z_1,z_2 !=0)

This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement -I: If a gas has compressibility factor (Z) greater than unity, then repulsive forces are dominant. Statement - II: Value of Z decreases with increase in pressure.

Read the following question and decide which of the given statements is are sufficient Question: The average marks of X,Y,Z is 180. what is X's mark? Statements: I :Y and Z together score 50 marks II:X and Z together score 60 marks.

Statement I: We have an equation involving the complex number z is |(z-3i)/(z+3i)| which lies on the x-axis.Statement II: The equation of the x -axis is y=3

Statement-1 : Let z be a complex number satisfying |z-3|lt=|z-1|,|z-3|lt=|z-5|,|z-i|lt=|z+i|a n d|z-i|lt=|z-5i| . Then the area of region in which z lies is 12 sq. unit. Statement-2 : Area of trapezium =1/2x (sum of parallel sides) x (distance between parallel sides) (a) Statement-1 is correct and Statement-2 is correct and Statement-2 is correct explanation of Statement-1. (b) Statement-1 and Statement-2 both are correct but Statement-2 is not correct explanation of Statement-1 (c) Statement-1 is false but Statement-2 is true. (d) Statement-1 is true but Statement-2 is false
