in an election between two candidates , one got 55 % of the total valid votes , 20 % of the votes were invalid . if the total number of votes was 2000 , the number of valid votes that the other candidate got , was :
"number of valid votes = 80 % of 2000 = 1600 valid votes polled by other candidate = 45 % of 2000 = ( 45 / 100 ) x 2000 = 900 answer = a"
multiply(multiply(subtract(const_1, divide(20, const_100)), subtract(const_1, divide(55, const_100))), 2000)
