1:1

Explanation:

Formula for range of a projectile is R=(u^2 sin 2 theta)/g where,u is the velocity of projection and theta is the angle of projection.

For,u be the same for both the bodies,

R_1 : R_2 = sin 2theta : sin 2(90-theta)=sin 2theta: sin(180-2theta)=sin 2 theta : sin 2theta=1:1 (as, sin(180-2theta)=sin 2theta)
