(i) Concave mirror
(ii) Linear magnification `= - ("Image distance")/("Object distance")`
`m= (-v)/(u)`
Object distance , `u = -15` ( u is always negative )
Image distance , `u= - 60 ` (v is negative for real image )
`m = - ((-60))/((-15))` `:. m = -4`
The minus sign in magnification shows that the image formed is real and inverted.
(iii) Distance between object and its image `=45 cm`
(iv) Ray diagram `:`

The image formed is real, inverted, magnified and beyond 2f
