Three real questions, as they appear.

Taken from the library as they are — not rewritten for this page. Two have a commission’s final key. For the third we hold no commission key, and you can see that before you answer it.

RPSC RAS Prelims · 2016 · Q36Commission’s final key

Identify the incorrect statement about Government of India Act 1919 :

Choose an answer. The reasoning opens once you have — on every question, not only this one.

The Government of India Act 1919 is known as the Montagu-Chelmsford Reforms (Mont-Ford Reforms), named after Edwin Montagu, the Secretary of State for India, and Lord Chelmsford, the Viceroy. In contrast, the Morley-Minto Reforms was the name given to the Indian Councils Act of 1909. The 1919 Act was enacted in 1919, took effect in 1921, and separated the central and provincial subjects under its devolution rules. Therefore, statement (2) is false and is the required incorrect statement.

Why each other option is not the key

(A)The Government of India Act 1919 was brought into actual operation in the year 1921.
(C)Edwin Montagu was the Secretary of State for India while Lord Chelmsford served as the Viceroy during the formulation of the 1919 Act.
(D)The 1919 Act demarcated and separated the central and provincial subjects to relax central control over the provinces.

RPSC RAS Prelims · 2016 · Q40Commission’s final key

Which one of the following legislative house can be abolished ?

Choose an answer. The reasoning opens once you have — on every question, not only this one.

Article 169 of the Constitution of India provides the constitutional mechanism for the abolition or creation of Legislative Councils (Vidhan Parishad) in States. Parliament can enact a law to abolish an existing Vidhan Parishad if the Legislative Assembly (Vidhan Sabha) of that State passes a resolution by a special majority (a majority of total membership and a two-thirds majority of members present and voting). In contrast, Lok Sabha and Vidhan Sabha can only be dissolved under Articles 85 and 174, while Rajya Sabha is a permanent body under Article 83(1) that cannot be dissolved or abolished. Thus, only the Vidhan Parishad can be abolished.

Why each other option is not the key

(A)Lok Sabha is a mandatory house of Parliament that can be dissolved before its term, but cannot be abolished.
(B)Rajya Sabha is a permanent chamber that is neither subject to dissolution under Article 83(1) nor capable of being abolished.
(D)Vidhan Sabha is an essential house of a state legislature that can be dissolved under Article 174(2)(b), but cannot be abolished.

BPSC CCE Prelims · 2023 · Q15Two models, agreed

The image formed by concave mirror is real, inverted and of the same size as that of the object. The position of the object should be

We hold no commission key for this paper — the blue label says so before you choose. Two models answered it separately and agreed.

For a spherical concave mirror, the image distance (v) and object distance (u) are governed by the mirror formula 1/f = 1/v + 1/u. When an object is placed at the centre of curvature (C), where object distance u = -2f = -R, reflected rays converge at an equal distance in front of the mirror (v = -2f). The linear magnification m = -v/u equals -(-2f)/(-2f) = -1, meaning the image is real, inverted, and identical in size to the object. Thus, the object must be located at the centre of curvature to produce an inverted image of the same size.

Why each other option is not the key

(A)Placing the object at the focus (F) forms an infinitely distant, highly magnified real image.
(C)Placing the object between the focus and centre of curvature forms an enlarged real image beyond C.
(D)Placing the object beyond the centre of curvature forms a diminished real image between F and C.
