Q1:(60/200)X100%=30%
Q2:(11000) / (110/100)=$10000
Q3:(6 800 000 X 2%)+6 800 000=6 936 000
Q2:(11000) / (110/100)=$10000
Q3:(6 800 000 X 2%)+6 800 000=6 936 000

Question 1
Original price: $200
Discounted price: $200-$60=$140
Percentage decrease= $60/$200 X 100%
= 30% decrease
Question 2
Increased salary = 110% = $11000
Therefore original salary = 100% = $10000
Question 3
Original population = 6 800 000
Yearly increase = 6 800 000 X 0.02 (2%)
= 136 000
Next year's population = 6 800 000 + 136 000
= 6 936 000
Original price: $200
Discounted price: $200-$60=$140
Percentage decrease= $60/$200 X 100%
= 30% decrease
Question 2
Increased salary = 110% = $11000
Therefore original salary = 100% = $10000
Question 3
Original population = 6 800 000
Yearly increase = 6 800 000 X 0.02 (2%)
= 136 000
Next year's population = 6 800 000 + 136 000
= 6 936 000
