Question

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%

Answer 1

The correct option is D

15.36%

Perimeter of E$=2\pi r=2\times 22/7\times 10=440/7m$
Cost of fencing of E$=440/7\times 22=Rs.1382.85$
Area of C = $15\times 15=225sq.m$
So, cost of flooring of C = $225\times 40=Rs.9000$
So, required %$=1382.85\times 100/9000$
=15.36% of flooring cost of C
