(2,4) is a point on a circle that has centre at the origin. Which of the following point(s) is/are also on the circle ?
 A. (2,-4) B. (-2,4) C. (4, -2) D. All of these Answer Report Discuss Option: D Explanation : Since the circle with centre at the origin, is symmetric about the X-axis, Y-axis, the line X = Y and the line X = - Y, the reflection of (2, 4) about these axes, will also be points on the circle.

The people of the planet Mars designed a scale for measuring the temperature in which water freezes at 100 units and boils at 250 units. The people of Jupiter designed a scale in which water freezes at 75 units and boils at 300 units. A temperature of 200 units in Mars will measure ___ in Jupiter.
 A. 300 B. 225 C. 250 D. 175 Answer Report Discuss Option: B Explanation : Translating so that both the scales start at the origin, and scaling so that the divisions in both scales coincide, we get the formula (M-100) x 225/150 =J -75, where M refers to the scale in Mars and J, to the scale in Jupiter. Putting M = 200, we get J = 225. Click on Discuss to view users comments. Write your comments here:
