medium Q4 of 15
Step-by-Step Solution
Step 1: Compute 60% of 250
60% of 250 = (60/100) × 250 = 0.6 × 250 = 150.Step 2: Compute 10% of 80
10% of 80 = (10/100) × 80 = 8.Step 3: Subtract the values
150 − 8 = 142.Final Answer:
142 → Option A.Quick Check:
60% = 3/5 → 3/5 of 250 = 150; minus 8 = 142 ✅
Quick Trick: Compute each percent term separately, then combine.
Common Mistakes:
- Subtracting percentages instead of subtracting percentage-values.
