(figures are not exact .Follow mode from R.S.Agarwal)

2.3+5+7+......n how many no. make the sum

480.(easy)

3.aqn based on simple algebra

x+y+z=0 then .............=?

A:we can expand that as ((x+y+z)^3+3xyz)/3xyz

so ans is 3

4.Total marks of an exam:500 A got 10% less than B.B got 25% more than C. C got 20% less than D.If A scored 300,score of D?
