Dear akash

projectile hit the plane horizontaly ,it means it hit at its hihest point

H= u2sin260 /2g

and R =u2sin120/g

or R/2 = u2sin120/2g

tan A =H/(R/2)   where A is the angel of plane

        =tan60 /2

         =√3/2

so range on incline plane =H/sinA

 

Put the value of H and SinA  you will get the result
