three numbers are in the ratio 2 : 3 : 5 and their average is 50 . the largest number is :
"explanation : let the numbers be 2 x , 3 x and 5 x , then , ( 2 x + 3 x + 5 x ) / 3 = 50 = > 10 x = 150 = > x = 15 . largest number 5 x = 5 * 15 = 75 answer : b"
add(multiply(multiply(2, 5), const_100), multiply(3, 5))
