• A. Rs. $48,000$; Rs. $45,000$
• B. Rs. $52,000$; Rs. $75,000$
• C. Rs. $66,000$; Rs. $35,000$
• D. Rs. $17,000$; Rs. $85,000$

Answer 1

The correct option is A Rs. $48,000$; Rs. $45,000$

Given, length of hall is $45$ m and width is $32$ m

Then area of hall $=$ $45\times 32=1440m^2$

Length of carpet $=$ $\frac{1440}{1.2}$ .....(given width of carpet is $1.2$ m)

Then cost of carpet $=$ $\frac{1440}{1.2}\times 40=$ Rs. $48000$

When cost of $80$ cm width at rate Rs. $25$ per meter

Then cost carpet $=$ $\frac{1440}{0.80}\times 25=$ Rs. $45000$
