Swarnavo Banerjee from Indian School Sohar, Sohar
Subject :IMO    Class : Class 4

Ans 1: (Master Answer)

Class : Class 1

(B)

2 star + moon = 1960

4 star + moon = 2780

Now, 2 star + 1960 = 2780

          2 star = 820

          1 star = 410

Also, 2 star + moon = 1960

         820+moon = 1960

          moon = 1960-820 = 1140

Therefore, 3 star + 3 moon = 1230+3420=4650

Actually you all got b because you only counted Anu's savings and not Gaurav's saving. I mean that Gaurav already has R12, so if anu gives him 12 more rupees then both of them have equal. Is a bit tricky but not complicated.
