A mixture of 100 pounds contains sand and iron dust. The ratio of sand and iron dust is 3:2. If 10 pounds of sand and 10 pounds of iron dust are added to the mixture. What is the new ratio of sand to Iron dust?
Sand :3
Iron Dust:2
Sand: 3/5 * 100= 60
Iron dust: 2/5* 100= 40
New value
sand = 60+10 =70
Iron Dust = 40+10 =50
New ratio
Sand : Iron Dust = 70:50 = 7:5
Answer is 7:5
