### Solutions

1. Total sales of copper in 2003 and 2004= 160+160= 320 tonnes
Average sales of silver in 2004 and 2005= (180+220)/2= 200 tonnes
Percentage= (320/200)*100= 160% (b)
2. Average sales of gold in 2002, 2004 and 2005 together= (60+110+80)/3=250/3=83 1/3 (b)
3. Sum of average sales of silver in 2002-2003 and copper in 2003-2004
= (110+160)/2+ (160+160)/2
=135+160=295
1.5 times 295= 1.5*295= 442.50 (c)
4. Sales of silver in all four years=670tonnes
Total sales of gold and copper in 2003-2004=500 tonnes
Percentage= (670/500)*100= 134% (d)
5. Sales of silver in 2003-2004=340
Difference between the average sales of copper and gold in 2002-2003 is(220+160)/2-(60+80)/2
=190-65=125
Ratio is 340:125=68:25(a)
