Answer:
The total number of voters was 7488
Step-by-step explanation:
Let us solve this question using the ratio method
∵ The ratio of yes votes to no votes was 4 to 5
∵ There were 4160 no votes
∵ We need to find the total number of votes
∵ The total of the ratio = 4 + 5 = 9
→ By using the ratio method
→ YES : NO : Total
→ 4 : 5 : 9
→ x : 4160 : y
→ By using the cross multiplication
∵ 5 × y = 4160 × 9
∴ 5y = 37440
→ Divide both sides by 5 to find y
∵
= 
∴ y = 7488
∵ y represents the total number of voters
∴ The total number of voters was 7488
I HAVE THE FOLLOWING APPROACH
WE KNOW THAT THE MEAN IS 17,
WE ADD ALL THE NUMBERS AND GET 142+A+B= 17*10
142+A+B=170
A+B=28
NOW MEDIAN IS 18,
WE HAVE 10 NUMBERS, THAT MEANS THE MEDIAN WILL BE (17+B)/2=18
B=19
A=9
THESE ARE YOUR NUMBERS
