CAT/1997
Question . 86
What is the area bounded by the two lines and the co-ordinate axes in the first quadrant?
I. The lines intersect at a point which also lies on the lines 3x – 4y = 1 and 7x – 8y = 5
II. The lines are perpendicular, and one of them intersects the y-axis at an intercept of 4
Explanatory Answer
Method of solving this CAT DILR Question from Data Sufficiency question
(c) Statement I gives us the point of Intersection of the two lines (3,2) statement II give us the equation of one line passing through (0, 4) & pt ( 3, 2) also since two lines are perpendicular, we can find its slope also . Hence we can find the area with the help of both the statements.
