Given that,
Object distance, u = -24 cm
Focal length, f = -10 cm
Now,
According to mirror formula
1 over v plus 1 over u equals 1 over f rightwards double arrow space v space almost equal to space minus 17 space c m
Thus, 
Magnification of concave mirror
h subscript i over h subscript o equals fraction numerator negative left parenthesis negative 17 right parenthesis over denominator negative 24 end fraction almost equal to negative 0.70 rightwards double arrow h subscript i equals negative 0.70 space cross times h subscript o
Now from this we can conlude that the image formed will be diminish, inverted and real.
