Answers With Explanation :

1.      (D)          

        Amount spent on labour

= (90/360)*1500000

      = 3, 75, 000

2.      (A) 

Amount spent on bricks, steel and cement

= [(54+54+72)/360]*100 = 50%

3.      (B) 

        % of amount spent on timber with respect to the amount spent on cement

        = (36/72)*100 = 50%

4.        (C)         

Amount spent on labour and supervision

= `[(90+54)/360]*1500000

= 6, 00,000

5.        (D)         

Required number of students

= (13 + 11) × 3600/100   = 864

6.        (B)         

Required number of students

= 15 × 3600/100 = 540

7.      (A) 

        15/18 × 100 = = 83.33 = 83% (Approx.)

8.      (C) 

        Ratio =(18 + 21)/ 13 =39/13= 3 : 1
