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.

dear but both triangle have same perpendicular and my answer is correct.
yes I understand but area of triangle formula is half*base*perpendicular. but the base is not given, what's given is a part of the base that is the problem thats why I am congused with your solution.
in this problem base and perpendicular both are given . it is matter what base you choose and if perpendicular is not drawn inside then you can draw it outside as well. Area is dependent on base how long it is and perpendicular that is drawn on it
