• A. Rs 136800
• B. Rs 216360
• C. Rs 178790
• D. Rs 211940
• E. None of these

Answer 1

The correct option is B Rs 216360

Area of hall = 23 $\times$ 29 = 667 $m^2$
Area of branch manager room
= 13 $\times$ 17 = 221 $m^2$
Area of pantry = 14 $\times$ 13 = 182 $m^2$
Area of record keeping
=21 $\times$ 13 = 273 $m^2$
Area of locker = 29 $\times$ 21= 609 $m^2$
Total flooring area
= (667 + 221+ 182 + 273 + 609) $m^2$
= 1952 $m^2$
Cost of wooden flooring = Rs 170 per $m^2$
Cost of marble flooring = Rs 190 per $m^2$
Cost of flooring of branch manger room = 221 $\times$ 170 = Rs37570
Cost of painting
= [2 (17 $\times$ 12 + 13 $\times$ 12) + 13 $\times$ 17 $\times$ 190
= [2 (204 + 156) + 221] $\times$ 190
= (2 $\times$ 360 + 221) $\times$ 190
= (720 + 221) $\times$ 190 = 941 $\times$ 190
= Rs 178790
Total cost = 178790 + 37570 = Rs 216360
