The correct answer is 8 years. We can find Ali's present age by setting up an equation based on the given condition about the reciprocals of his past and future ages.

Step-by-Step Solution

Let Ali's present age be x years.

• His age 2 years ago was: x − 2
• His age 4 years from now will be: x + 4

The sum of the reciprocals of these two ages is given as 1/4:

1/(x − 2) + 1/(x + 4) = 1/4

To solve, we find a common denominator:

• (x + 4) + (x − 2) over (x − 2)(x + 4) = 1/4
• (2x + 2) / ((x − 2)(x + 4)) = 1/4

Cross‑multiply:

• 4(2x + 2) = (x − 2)(x + 4)
• 8x + 8 = x² + 2x − 8
• Bring all terms to one side: 0 = x² − 6x − 16

Factor the quadratic:

• x² − 6x − 16 = (x − 8)(x + 2) = 0
• So x = 8 or x = −2

Since age cannot be negative, Ali's present age is 8 years.

Verification

Check the condition with x = 8:

• Age 2 years ago = 6; reciprocal = 1/6
• Age 4 years from now = 12; reciprocal = 1/12
• Sum = 1/6 + 1/12 = (2 + 1)/12 = 3/12 = 1/4 ✔

Why Other Options Are Incorrect

• 6 years: Past age = 4, future = 10; sum of reciprocals = 1/4 + 1/10 = 0.35, not 0.25.
• 10 years: Past = 8, future = 14; sum = 1/8 + 1/14 ≈ 0.196, not 0.25.
• 12 years: Past = 10, future = 16; sum = 1/10 + 1/16 = 0.1625, not 0.25.

Therefore, the only age that satisfies the equation is 8 years, making it the correct answer.

Among the options, Pfizer-BioNTech is one of the most widely recognized and internationally approved COVID-19 vaccines. It has received extensive regulatory approvals and global distribution. While Moderna is also recognized, Pfizer holds a broader international presence and recognition.

The correct answer is 25. The sequence 20, 25, 30, ..., 140 forms an arithmetic progression (AP) with the following parameters:

• First term (a) = 20
• Common difference (d) = 5
• Last term (Tₙ) = 140

We use the formula for the nth term of an AP: Tₙ = a + (n − 1)d

Substituting the values: 140 = 20 + (n − 1) × 5

• 140 − 20 = (n − 1) × 5
• 120 = (n − 1) × 5
• 120 ÷ 5 = n − 1
• 24 = n − 1
• n = 25

Options 22, 23, and 24 do not satisfy the formula, so the correct answer is 25.

The correct answer is Quaid-e-Azam Muhammad Ali Jinnah. He became the first President (President of the Assembly) of Pakistan's Constituent Assembly on 11 August 1947. After his death in 1948, Maulvi Tamizuddin Khan was elected President (Speaker) of the Assembly.

Why the Other Options Are Incorrect

• Molvi Tamiz-ud-Din: Became President of the Assembly after Jinnah's death.
• Liaquat Ali Khan: First Prime Minister of Pakistan.
• Khawaja Nazimuddin: Served as Governor-General and later Prime Minister.

Therefore, Quaid-e-Azam Muhammad Ali Jinnah is the correct answer.
