Answer 2

Answer:

The average age of Gandhi,Nehuru and Sastri is 30yrs.

Step-by-step explanation:

[Gandhi(G) + Nehuru(n) + Sastri(n) + Giri(g) + Bhagat(b)]/5=28--(1)

also given that, (g+b) / 2=25

                 g+b=50---(2)

Apply (2) in (1), we get that

               (G+n+s+50)/5=28

                   G+n+s+50=140

                      G+n+s=90

      Average, (G+n+s)/3=90/3=30
