two numbers a and b are such that the sum of 8 % of a and 4 % of b is two - third of the sum of 6 % of a and 8 % of b . find the ratio of a : b .
"explanation : 8 % of a + 4 % of b = 2 / 3 ( 6 % of a + 8 % of b ) 8 a / 100 + 4 b / 100 = 2 / 3 ( 6 a / 100 + 8 b / 100 ) ⇒ 8 a + 4 b = 2 / 3 ( 6 a + 8 b ) ⇒ 24 a + 12 b = 12 a + 16 b ⇒ 12 a = 4 b ⇒ ab = 4 / 12 ⇒ a : b = 1 : 3 answer : option d"
divide(subtract(divide(multiply(divide(8, const_100), 4), const_3), divide(4, const_100)), subtract(divide(8, const_100), divide(multiply(divide(6, const_100), 4), const_3)))
