**Q. (1-5): Study the given table carefully to answer the following questions.**

**Q1. What is the cost of flooring of A?**

a) Rs.4000

b) Rs.4600

c) Rs.4800

d) Rs.5000

e) Rs.4400

**1. Option C**

**A is a triangle**

**So, area of A = 1/2 × 16 × 12 = 96 m**

^{2}**So, cost of flooring of A = 96 × 50 = Rs.4800**

**Q2.What is the difference between the cost of fencing of C and that of B?**

a) Rs.180

b) Rs.120

c) Rs.240

d) Rs.360

e) Rs.480

**2. Option A**

**Perimeter of B = 2 (10 + 20) = 60 m**

**So, cost of fencing of B = 60 × 15 = 900**

**Perimeter of C = 4 × 15 = 60 m**

**So, cost of fencing of C = 60 × 18 = Rs.1080**

**So, required difference = 1080 – 900 = Rs.180**

**Q3. What is the ratio of the cost of flooring to that of fencing of field D?**

a) 4 : 1

b) 6 : 1

c) 8 : 1

d) 9 : 1

e) 5 : 1

**3. Option D**

**Area of D = Base × Height**

**= 20 × 12 = 240m ^{2}**

**So, cost of flooring of D= 240 × 60 = Rs.14400**

**Perimeter of D = 2 (20 + 12) = 64 m**

**So, cost of fencing of D = 64 × 25 = Rs.1600**

**So, required ratio = 14400 : 1600 = 9 : 1**

**Q4. The cost of fencing of field E is approximately what percent of the cost of flooring of field C?**

a) 10.5%

b) 19.46%

c) 18.71%

d) 15.36%

e) 13.82%

**4. Option D**

**Perimeter of E = 2πr = 2 × 22 / 7 × 10 = 440 / 7 m**

**Cost of fencing of E = 440 / 7 × 22 = Rs.1382.85**

**Area of C = (15) ^{2}= 225m^{2}**

**So, cost of flooring of C = 225 × 40 = Rs.9000**

**So, required % = 1382.85 × 100 / 9000**

**= 15.36% of flooring cost of C.**

**Q5. The cost of fencing of field C is what percent of the cost of fencing of field D?**

a) 87.54%

b) 67.5%

c) 72.13%

d) 54.36%

e) 46.5%

**5. Option B**

**Fencing cost of C = Rs.1080**

**Fencing cost of D = Rs.1600**

**Required % = 1080 / 1600 × 100 = 67.5%**
