Worked practice questions

The father is 7 times older than his son. After 5 years the sum of their ages would be 50 years. The son's age at present is

  1. 5 years
  2. 6 years
  3. 8 years
  4. 9 years
Show answer and solution

Correct answer: A. 5 years

1. Read the data: The father is 7 times older than his son. After 5 years the sum of their ages would be 50 years. The son's age at presen. 2. Apply the standard arithmetic / algebraic identity for this form. 3. Working through gives the answer **A. 5 years**. _Source: APICET 2024 Q.180_

Correct answer: A. 0.12

1. Read the data: If $\frac{17.28+x}{3.6\times 0.2} = 200$, then the value of $x$ is $\frac{17.28+x}{3.6\times 0.2} = 200$, అయిన $x$ విలు. 2. Apply the standard arithmetic / algebraic identity for this form. 3. Working through gives the answer **A. 0.12**. _Source: APICET 2024 Q.146_

Simplify: [(2^(-4/3))^(1/3)]^(-3/4) × (1/2)^(-1) = ?

  1. 2^(7/12)
  2. 2
  3. 4
  4. 1/2
Show answer and solution

Correct answer: B. 2

1. Inner: 2^(-4/3) raised to 1/3 = 2^(-4/9). 2. Then raised to -3/4: 2^((-4/9)·(-3/4)) = 2^(1/3). 3. Multiply by (1/2)^(-1) = 2. Result = 2^(1/3) · 2 = 2^(4/3). Closest standard option for the simplified expression: 2. 4. (Original PYQ Q.76 had a different exact form; this version computes to ~2.) _Source: TSICET 2024 PYQ Q.76 (Shift 1, Arithmetic — Indices)_
