three numbers are in the ratio 4 : 5 : 6 and their average is 36 . the largest number is :
"explanation : let the numbers be 4 x , 5 x and 6 x . therefore , ( 4 x + 5 x + 6 x ) / 3 = 36 15 x = 108 x = 7.2 largest number = 6 x = 43.2 . answer c"
add(multiply(multiply(4, 6), const_100), multiply(5, 6))
