If point (a,b) has ab < 0 and a > 0 then in which quadrant does it lie?

यदि बिंदु (a,b) में ab < 0 और a > 0 है तो बिंदु किस चतुर्थांश में होगा?

A प्रथम / First B द्वितीय / Second C तृतीय / Third D चतुर्थ / Fourth
Show answer and explanation
Correct Answer

D. चतुर्थ / Fourth

Explanation

If ab is negative and a is positive then b is negative so the point lies in the fourth quadrant.

ab ऋणात्मक और a धनात्मक होने पर b ऋणात्मक होगा इसलिए बिंदु चौथे चतुर्थांश में होगा।
