Solution:
Directions (Q. 1-5):

1). The price per 1g of each metal in all cities is shown below:
Metal index

From the table, we see that Chennai has the highest Metal Index.

2). Average Price of Gold =(432.5+412.5+300+307+298.5)/5=1750.5/5=350.1
Average Price of Silver =(75+71.75+84.5+101.5+88)/5=420.75/5=84.15
Difference =350.1 – 84.15 =265.95

3). 45g of gold in Delhi = 45 × 307 =13815
After margins, its worth 90% of 13815 = 12433.5
Iron returned =12433.5 /18= 690.75g ~=691g.

4).
From the table, we have that Mumbai saves the most per 0.8g of aluminium, which means it will save the most per 100kg as well.

5).  Cost = 4 × 307 + 6 × 101.5 + 50×(18+88)=7137

6).  Amount earned by Person-C in February =4000
Amount earned by Person-C in March =10000
Percentage increase =[(10000 – 4000)/4000] ×100=150%

7). Total amount earned by person A in all months together=(8+12+14+3+9+11)thousands =57000
Average =57000/6 =Rs 9500

8). the amount earned by Person –C in May =12000
The amount earned by Person-A in March =14000
Amount earned by Person-B in April=4000
Ratio =12 : 14 : 4 =6 :7:2

9). The total amount earned by Person-B over all the months together =(4+9+7+4+6+12)thousands=42000
The amount earned by person-C in April =11000
Difference =42000-11000=31000

10).Total amount earned by all the three persons together in January =8000 + 4000 + 9000 =21000
The total amount earned by all the three persons together in March =14000 + 7000 + 10000 =31000
Required percentage=21000/31000 × = 67.74%
