According to what is given in the question,I assume it to be an ideal mirror with small aperture.We know that focal length is given by
where R is the radius of curvature of the mirror.
So the focal length of the lens is 0.25 m or 25 cm
I hope it Helps

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
