**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%

A is a triangle

So, area of A = 1/2 × 16 × 12 = 96 m

So, cost of flooring of A = 96 × 50 = Rs.4800

So, area of A = 1/2 × 16 × 12 = 96 m

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

**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

Area of D = Base × Height

= 20 × 12 = 240m

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

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)

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

So, required % = 1382.85 × 100 / 9000

= 15.36% of flooring cost of C.

Fencing cost of C = Rs.1080

Fencing cost of D = Rs.1600

Required % = 1080 / 1600 × 100 = 67.5%

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

**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

**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.

**5. Option B**Fencing cost of C = Rs.1080

Fencing cost of D = Rs.1600

Required % = 1080 / 1600 × 100 = 67.5%
