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.

Eduncle Best Answer
Inclusive Fitness = Direct Fitness + Indirect Fitness = (Survival of offspring) × (r for parent-offspring) + (Survival of non-descendant kin) × (the proper r for each type of relationship) In this question Offspring survived = 5 and coefficient of relatedness (r) = 0.5, Niece+nephews = 5 and r = 0.25, hence inclusive fitness = (5*0.5) + (5*0.25) = 2.5 + 1.25 = 3.75.
