1.2

Show answer and solution

Correct answer: A. 0.89

1. Apply BODMAS: 0.284 ÷ 0.4 = 0.71, then 0.71 × 0.8 = 0.568. 2. Now 0.36 + 0.568 − 0.038. 3. = 0.928 − 0.038 = 0.89. _Source: RRB Group D CEN-02/2018 PYQ, Q.34._

Evaluate: 75 ÷ [35 − {63 − (79 − 54 ÷ 9 × 6)}].

Show answer and solution

Correct answer: C. 5

1. Innermost: 54 ÷ 9 × 6 = 6 × 6 = 36, so 79 − 36 = 43. 2. Then 63 − 43 = 20, and 35 − 20 = 15. 3. 75 ÷ 15 = 5. _Source: RRB Group D CEN-02/2018 PYQ, Q.91._
