in the mock qualifier solution pdf, test question no. 13, can anyone explain why the average of section A and B are taken as 48 and 48? whereas they are 45 and 50respectively...?
is the given answer/solution wrong??

its the averge of A and B together(a+b/n1+n2) whereas 45 and 50 are separate avg of A and B(a/n1 and b/n2)
