 Question 50:

5% of 10% of 175 grams is equal to:
(a) 8.75 gm (b) 0.5 gm (c) 0.875 gm (d) 17.5 gm

Step 1: Find 10% of 175

10% of 175=0.1×175=17.5 grams10\% \text{ of } 175 = 0.1 \times 175 = 17.5 \, \text{grams}

Step 2: Find 5% of 17.5

5% of 17.5=0.05×17.5=0.875 grams5\% \text{ of } 17.5 = 0.05 \times 17.5 = 0.875 \, \text{grams}

✅ Answer: (c) 0.875 gm

Tip for fast calculation:

  • Convert percentages to decimals and multiply step by step:

5% of 10%=0.05×0.1=0.0055\% \text{ of } 10\% = 0.05 \times 0.1 = 0.005 0.005×175=0.8750.005 \times 175 = 0.875

This avoids multiple small steps and reduces errors.
