Simplify: (√100 + 30% of 100) ÷ (2/5 of 25)
easy Q13 of 15
Step-by-Step Solution
Step 1: Evaluate the square root
√100 = 10.Step 2: Compute 30% of 100
30% = 30/100, so 30.Step 3: Form the numerator
10 + 30 = 40.Step 4: Compute denominator
(2/5) × 25 = 10.Step 5: Divide
40 ÷ 10 = 4.Final Answer:
4 → Option C.Quick Check:
4 × 10 = 40 (correct) ✅
Quick Trick: Convert percent to decimal/fraction and simplify fraction multiplications before dividing.
Common Mistakes:
- Forgetting to multiply the denominator fraction correctly.
