three numbers are in the ratio 1 : 3 : 6 and their average is 100 . the largest number is :
"explanation : let the numbers be x , 3 x and 6 x , then , ( x + 3 x + 6 x ) / 3 = 100 = > 10 x = 100 * 3 = > x = 30 largest number 6 x = 6 * 30 = 180 answer : a"
add(multiply(multiply(1, 6), const_100), multiply(3, 6))
