easy Q12 of 15
Step-by-Step Solution
Step 1: Convert percent and compute
60% of 150 = (60/100) × 150 = 0.6 × 150 = 90.Step 2: Write the equation
90 = ? × 30.Step 3: Solve for ?
? = 90 ÷ 30 = 3.Final Answer:
3 → Option B.Quick Check:
3 × 30 = 90, which equals 60% of 150 ✅Explanation for Beginners:
First find the numeric value of the percentage of the base. Then treat the result as a product and undo multiplication by dividing by the known multiplier to get the unknown.
Quick Trick: Find percent value first (0.6×150), then divide by the given multiplier.
Common Mistakes:
- Treating 60% as 60 (not 0.6) or forgetting to divide by 30 at the end.
