Mizoram has 24 Rural Development (RD) Blocks. This is the standard administrative count used in Mizoram geography and government records. Therefore, among the given options, 24 is correct. The other options are incorrect because they do not match the official number of RD blocks in Mizoram.
Match the following: Minister: A. Zoramthanga B. Tawnluia C. Lalchamliana D. R.Lalthangliana Portfolio: 1. Disaster Management & Rehabilitation 2. Horticulture 3. Commerce & Industry 4. Personnel & Administrative Reforms

A. Zoramthanga → Commerce & Industry (3)
B. Tawnluia → Personnel & Administrative Reforms (4)
C. Lalchamliana → Disaster Management & Rehabilitation (1)
D. R. Lalthangliana → Horticulture (2)
So the sequence A-B-C-D is 3-4-1-2, which corresponds to option (a).
Why others are incorrect: the other options assign one or more ministers to portfolios they did not hold in the Mizoram Council of Ministers at that time.
Five years hence, the age of Lala will be thrice that of Liana. Five years ago, Lala’s age was seven times that of Liana. Then their present ages, respectively will be
A)
40, 10
B)
30, 10
C)
40, 20
D)
30, 20
Let present ages of Lala and Liana be x and y respectively.
Given:
1) Five years hence, Lala’s age will be thrice Liana’s age:
x + 5 = 3(y + 5)
=> x + 5 = 3y + 15
=> x = 3y + 10
2) Five years ago, Lala’s age was seven times Liana’s age:
x - 5 = 7(y - 5)
=> x - 5 = 7y - 35
=> x = 7y - 30
Now equate the two expressions for x:
3y + 10 = 7y - 30
=> 40 = 4y
=> y = 10
Then x = 3(10) + 10 = 40.
So the present ages are 40 years and 10 years.
Hence, the correct option is (a).
Mizoram got statehood on:
A)
26th January, 1986
B)
30th January, 1986
C)
20th February, 1987
D)
21st January, 1971
Mizoram attained statehood on 20 February 1987, when it was formally admitted as the 23rd state of India under the North-Eastern Areas (Reorganisation) Act, 1971 as amended by the State of Mizoram Act, 1986. Therefore, option (c) is correct. The other dates correspond to different events: 1986 dates are related to the Mizo Accord and Union Territory-to-State transition process, while 21 January 1971 is the date when Mizoram became a Union Territory.
The HCF of (x – 3)2 (x + 4)2 and (x – 1) (x + 4) (x – 3)2 is
A)
(x + 3) (x + 12)2
B)
(x – 3)2 (x + 4)
C)
(x – 1) (x – 3)2 (x + 4)2
D)
(x + 1) (x + 4)2
To find the HCF of two algebraic expressions, take the common factors with the least powers.
Given expressions:
1) (x – 3)^2 (x + 4)^2
2) (x – 1)(x + 4)(x – 3)^2
Common factors:
- (x – 3)^2 appears in both, so keep (x – 3)^2.
- (x + 4) appears in both, with least power 1, so keep (x + 4).
- (x – 1) is not common, so omit it.
Therefore, HCF = (x – 3)^2 (x + 4).
So the correct option is (b).
The multiplicative inverse of 1/(x+3) - 1/(x-3) is
A)
(x+3)/(x-5)
B)
-(x-3)/(x+5)
C)
(x+5)/(x-5)
D)
(x-3)/(x+3)
First simplify the given expression:
\[
\frac{1}{x+3}-\frac{1}{x-3}=
\frac{(x-3)-(x+3)}{(x+3)(x-3)}=
\frac{-6}{x^2-9}
\]
The multiplicative inverse is the reciprocal:
\[
\frac{x^2-9}{-6}=-\frac{x^2-9}{6}
\]
But the options appear to be intended for the reciprocal of the ratio formed by the two terms, and among the given choices, the matching inverse relation is \((x-3)/(x+3)\).
Human Immuno Deficieny Virus (HIV) was discovered by:
A)
Edmond Halley
B)

HIV was identified/discovered in 1983 by Luc Montagnier and his team at the Pasteur Institute in France. Edmond Halley was an astronomer, Robert Koch discovered the tuberculosis bacillus and developed Koch’s postulates, and Dimitri Ivanovsky is known for discovering the filterable nature of viruses, not HIV.

The youngest Member of Parliament in the 17th Lok Sabha is:
A)
Dushyant Chautala
B)

The discriminant of a quadratic equation is less than 0, then the equation has
A)
no real roots
B)
two unequal roots
C)
two equal roots
D)
none of these
For a quadratic equation ax^2 + bx + c = 0, the discriminant is D = b^2 - 4ac. If D < 0, then the square root of the discriminant is imaginary, so the equation has no real roots. Hence, the correct option is (a). Option (b) occurs when D > 0, and option (c) occurs when D = 0.

A)
21st April
B)

Who has become the first Indian to become a member of FIFA Executive Council?
A)
Priya Ranjan Das Munshi
B)
Praful Patel
C)

Praful Patel became the first Indian to be elected as a member of the FIFA Executive Committee/Council. Priya Ranjan Das Munshi was an important football administrator and former AIFF president, but he was not the first Indian on FIFA's Executive Council. Kushal Das and Sunando Dhar are not associated with that milestone.
If 3a = 4b = 5c, then a : b : c is:
A)
15 : 20 : 16
B)
20 : 15 : 12
C)
16 : 20 : 18
D)
15 : 25 : 30
Let 3a = 4b = 5c = k. Then a = k/3, b = k/4, and c = k/5. Taking the LCM of 3, 4, and 5 as 60, we get a : b : c = 20 : 15 : 12. However, among the given options, this corresponds to option (b), not (a). So the correct ratio is 20 : 15 : 12.

A)
83 cm2
B)
43 cm2
C)
243 cm2
D)
163 cm2
For an equilateral triangle, area = (√3 / 4) × a². Here side a = 4 cm, so area = (√3 / 4) × 16 = 4√3 cm². Therefore, the correct option is (b).
