TCS NQT Style Practice Questions

Practice Question 1

If '+' means '*', '-' means '/', '*' means '+' and '/' means '-', evaluate: 10 + 2 - 4 * 3.

A) 8
B) 6
C) 12
D) 10

Correct Answer: A) 8

Step-by-step Solution: Replace symbols: 10 * 2 / 4 + 3. Apply BODMAS: 10 * (2/4) + 3 = 10 * 0.5 + 3 = 5 + 3 = 8.

Practice Question 2

Substitute: P means '+', Q means '-'. Find 12 P 8 Q 5.

A) 15
B) 25
C) 20
D) 12

Correct Answer: A) 15

Step-by-step Solution: 12 + 8 - 5 = 20 - 5 = 15.
