Question

UpStudy AI · Accepted Answer

**a) 10% of Rs 50**

Calculate $$10\%$$ as a decimal:
$$
10\% = \frac{10}{100} = 0.1
$$
Then multiply by 50:
$$
0.1 \times 50 = 5
$$
Thus, $$10\%$$ of Rs 50 is **Rs 5**.

**b) 20% of Rs 80**

Calculate $$20\%$$ as a decimal:
$$
20\% = \frac{20}{100} = 0.2
$$
Then multiply by 80:
$$
0.2 \times 80 = 16
$$
Thus, $$20\%$$ of Rs 80 is **Rs 16**.

**c) 25% of 40 students**

Calculate $$25\%$$ as a decimal:
$$
25\% = \frac{25}{100} = 0.25
$$
Then multiply by 40:
$$
0.25 \times 40 = 10
$$
Thus, $$25\%$$ of 40 students is **10 students**.

---

**d) 30% of 70 people**

Calculate $$30\%$$ as a decimal:
$$
30\% = \frac{30}{100} = 0.3
$$
Then multiply by 70:
$$
0.3 \times 70 = 21
$$
Thus, $$30\%$$ of 70 people is **21 people**.

---

**e) 40% of 60 km**

Calculate $$40\%$$ as a decimal:
$$
40\% = \frac{40}{100} = 0.4
$$
Then multiply by 60:
$$
0.4 \times 60 = 24
$$
Thus, $$40\%$$ of 60 km is **24 km**.

---

**f) 50% of 90 kg**

Calculate $$50\%$$ as a decimal:
$$
50\% = \frac{50}{100} = 0.5
$$
Then multiply by 90:
$$
0.5 \times 90 = 45
$$
Thus, $$50\%$$ of 90 kg is **45 kg**.

---

**g) 60% of 100 boys**

Calculate $$60\%$$ as a decimal:
$$
60\% = \frac{60}{100} = 0.6
$$
Then multiply by 100:
$$
0.6 \times 100 = 60
$$
Thus, $$60\%$$ of 100 boys is **60 boys**.

---

**h) 70% of 20 girls**

Calculate $$70\%$$ as a decimal:
$$
70\% = \frac{70}{100} = 0.7
$$
Then multiply by 20:
$$
0.7 \times 20 = 14
$$
Thus, $$70\%$$ of 20 girls is **14 girls**.

---

**i) 80% of 50 eggs**

Calculate $$80\%$$ as a decimal:
$$
80\% = \frac{80}{100} = 0.8
$$
Then multiply by 50:
$$
0.8 \times 50 = 40
$$
Thus, $$80\%$$ of 50 eggs is **40 eggs**.
**Calculations:** - **a) 10% of Rs 50:** Rs 5 - **b) 20% of Rs 80:** Rs 16 - **c) 25% of 40 students:** 10 students - **d) 30% of 70 people:** 21 people - **e) 40% of 60 km:** 24 km - **f) 50% of 90 kg:** 45 kg - **g) 60% of 100 boys:** 60 boys - **h) 70% of 20 girls:** 14 girls - **i) 80% of 50 eggs:** 40 eggs
