Answers

1. Solution: Total flooring area with marble = locker area + record keeping + pantry = 182+273 +609 = 1064 sqm

Cost of flooring = 1064 × 190 Total flooring area with wooden = Branch Manager room + Hall = 221 + 667 = 888 sqm

Cost of flooring = 888 × 170

Ratio= 888 × 170: 1064 × 190

= 888 ×17: 1064 ×19 = 15096 : 20216 = 1887: 2527 Ans: 3

2. Solution:

Cost of flooring of branch manager room

=221 × 170= Rs. 37570 Cost of painting

= [2(17 × 12+ 13 × 12)+ 13 x 17] × 190

= [2( 204 + 156) + 221] × 190= (2 × 360 + 221) × 190

= (720 + 221) × 190 = 941 × 190 = Rs. 178790 Total cost = 178790 + 31570 = Rs.216360 Ans: (5)

3. Solution: Total area of bank = 2000 sqm Total flooring area = 1952 sqm Remaining area = 2000 - 1952 = 48 sqm

∴ Cost of carpeting = 48 × 110 = Rs.5280 Ans: (5)

4. Solution: Area not to be renovated = 48 sq m

∴ Reqd % = 482000× l00 = 2.4% Ans: 2 10. What is the total cost of renovation of the hall for customer transaction and the locker area? (1) Rs. 2, 29,100 (2) Rs. 2, 30,206 (3) Rs. 2, 16,920 (4) Rs. 2, 42,440 (5) None of these Solution: Cost of renovation of hall + locker area

= 667 × 170 + 609 × 190 = 113390 + 115710= Rs. 229100 Ans: (1)

5. Solution: Cost of renovation of hall + locker area

= 667 × 170 + 609 × 190 = 113390 + 115710= Rs. 229100 Ans: (1
