Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Firstly, I would like to mention that the axial tilt of Venus is 177.3 not 117 degrees. Yes, it's confusing that the axial tilt of Venus is 177.3 degrees and of Uranus is 98 degrees but still Uranus is considered as the planet with most tilted planet. The answer is very simple, rotational axis of any planet is a line which is perpendicular to the equatorial plane, not if will rotate any line by 177 degrees and 98 degrees which will be most tilted? If you will rotate any line by 177 degrees then after rotation the final tilt would be just 3 degrees (180-177), on the second hand if you will rotate any line by 98 degrees then final axial tilt will be 82 degrees (180-98). That's why Uranus is considered as planet with most tilted axis. Any line (axis in this case) remains unchanged after 180 degrees rotation. For more clarification, I have attached an image. Please take a look and compare the tilt of different planets, you will get it. In case of any clarification, feel free to ask.
thank yoy sir..
so we can say that the more the angle is close to 90°, more is the tilt
Yes, in general you can say. The reason why axial tilt of Venus and Uranus is greater than 90 is because of there unusual direction of rotation. All planets except Venus and Uranus rotates anti-clockwise whereas Venus and Uranus rotates clockwise. More specifically Uranus rolls on its side as it orbits the Sun.
