Awesome Sravani..
Actually a friend of mine needs some boost.. and she happens to be a reddy.. so was showing her your posts :).. too good a boost for her.
well.. many would want to know how the GMAT was beaten, but there are also a chosen few, who dont know what to do and how to do. Probably this would help them :)
its simple...
draw 3 rows of circles..5 in each row.. you wud find that if u place another circle, 1 circle tuches 4 other circles. so there are 8 oranges in second row..
now 8 circles can support only 3 circles. if 4 circles were to support 1 circle.
