The IAS Map — BPSC ke solved papers, har sawal ki wajah ke saath

Ye baaki PDF se alag kyun hai

Bihar ke sawal ginne padte hain

66th ke paper me 150 me se 28 sawal Bihar ke the — Polity se zyada. Sheohar, Phalgu, Kunwar Singh, Saat Nishchay. Free wala paper download karke khud gin lijiye; hum keh rahe hain isliye maan lene ki zaroorat nahi.

150

Poora paper, ek bhi sawal chhoota nahi

Selected questions nahi. Q1 se Q150 tak sab, official answer key ke saath, aath sections me baante hue. Jo sawal aapko mushkil laga, wo bhi ismein hai.

Aath page. Ek baithak.

Har jawab ke saath ek line ka reason — formula, ya wo ek fact jispe sawal tika tha. Poora paper aath page me. Padhne ke liye nahi, exam se pehle dohrane ke liye banaya gaya hai.

Andar aisa dikhta hai

66th ke paper se do sawal, jaise ke taise. Yahi format saare 150 me hai.

Q16. The pH of a solution changes from 3 to 6. The H⁺ ion concentration will:

(A) increase 3 times (B) decrease 3 times (C) decrease 10 times (D) decrease 1000 times (E) None / More than one

Ans: (D) decrease 1000 times

Exp: pH = −log[H⁺]. From pH 3 (10⁻³) to pH 6 (10⁻⁶), the [H⁺] ion concentration decreases by 10³ = 1000 times.

Q141. The missing number in sequence 4, 18, 48, 100, ?, 294, 448 is:

(A) 94 (B) 164 (C) 180 (D) 192 (E) None / More than one

Ans: (C) 180

Exp: Pattern: n³ − n². 2³−2²=4, 3³−3²=18, 4³−4²=48, 5³−5²=100. For n=6: 216 − 36 = 180.

Har sawal isi tarah — sawal, options, official key ka jawab, aur ek line ka reason. Saare 150. Phone pe padhne layak, print karne layak.

Chhote sawal
