Detailed Solution

Given 2 statements.
Assertion: If three angles of a quadrilateral are 130°, 70° and 60°, then the fourth angles is 100°.
Reason: The sum of all the angle of a quadrilateral is 360°.
Let the unknown angle = x.
As, sum of all angles of a quadrilateral is 360 o  .
130 o + 60 o + 70 o +x= 360 ° o 260 o +x= 360 o x= 360 o 260 o x= 100 o  
The unknown angle is 100 o  .
Both assertion (A) and reason (R) are true and reason (R) is a correct explanation of assertion (A).
Hence, option 1 is correct.
