Numerical Ability - Simplification & Approximation
Simplify: 80 − { 6 × (14 ÷ 7) }
Simplify: 80 − { 6 × (14 ÷ 7) }
medium Q5 of 15
Step-by-Step Solution
Step 1: Solve the innermost bracket
(14 ÷ 7) = 2.Step 2: Apply multiplication
6 × 2 = 12. Expression becomes 80 − 12.Step 3: Perform subtraction
80 − 12 = 68.Final Answer:
68 → Option D.Quick Check:
(14 ÷ 7 = 2, 6 × 2 = 12, 80 − 12 = 68) ✅
Quick Trick: Deepest bracket first, then ×, then −.
Common Mistakes:
- Subtracting 80 − 6 first.
