1.	A tall person 'A' anda short person 'B' stood before a plane mirror. 'A' stands 1.25 metres behind 'B' . If the distance between 'B' and the plane mirror is 50 cm , then the distance between 'A' and his image in the mirror is _______ .
Answer» 4 CM 3.5 cm 4.5 cm 3.75 cm Solution :DISTANCE between the plane mirror and B=50 cm =0.5 m Distance between A and B =1.25 m . Therefore, distance between the plane mirror and A=1.25 m + 0.5 m =1.75 m Therefore, distance between A and his IMAGE in the mirror in the mirror `=2xx1.75 `m `=3.5 m` Hence, the CORRECT OPTION is (b).
