Step-by-step explanation:
3.5% of listeners rated the song as 1 star
49 listeners rated the song as 1 star
49 listeners = 3.5% of listeners
we want to find 100% of listeners. we can do this by multiplying both sides of the equation by 100/3.5, getting one side to 100% and the other to what it is equal to
49 * 100/3.5 listeners = 100% of listeners = 1400
Answer:
Let ten's place digit =x and unit place digit =y
Number=10x+y
x+y=5 ...(i)
10x+y−9=10y+x
9x−9y=9x−y=1 ...(ii)
from (i) and (ii) we get,
x=3,y=2
∴Number=10×3+2=32.
