the ratio of three numbers is 6 : 7 : 5 and their sum is 108 . the second number of the three numbers is ?
"explanation : 6 : 7 : 5 total parts = 18 18 parts - - > 108 1 part - - - - > 6 the second number of the three numbers is = 7 7 parts - - - - > 42 answer : option b"
sqrt(divide(108, add(power(5, const_2), add(power(6, 7), power(7, 7)))))
