Let a and be the two numbers. We are given that
a:b = 4:5
This gives the equation
a = 4b/5…………………………………………………………………………..(1)
Sum of a and b is given to be 540. This gives another equation
a + b = 540……………………………………………………………………….(2)
Substituting for a from (1) into (2),
4b/5 + b = 540
Or, b(4/5 +1 ) = 540
Or, b x 9/5 = 540
Or, b = 540 x 5/9 = 9x60 x 5/9 = 60 x 5 = 300
From (2), a = 540 - b = 540 -300 = 240
Thus, the two numbers are 300 and 240. 300 being greater than 240,
a:b = 4:5
