Question

Three numbers are in a ratio of 4:5:6.If the sum of the largest and the smallest equals the sum of the third and 55,find the number???

Answer 1

given,
ratio of numbers=4:5:6
let first number =4x
second number =5x
and third number=6x
also given that sum of largest and smallest number is equal to 55
so,
6x+4x=55
10x=55
so x=55/10
so x =5.5
so first number=4x=4(5.5)=22
second number=5x=5(5.5)=27.5
& third number =6x=6(5.5)=33...
