500,000

Step-by-step explanation:

Total sum of money = x

Ratio = 4:5

= 4+5

= 9

Taiwo = 4/9 × x

400,000 = 4x/9

400,000 × 9 = 4x × 1

3,600,000 = 4x

Divide both sides by 4

x = 3,600,000/4

x = 900,000

Kehinde = 900,000 - 400,000

= 500,000

Kehinde's money can also be calculated as

Kehinde = 5/9 × 900,000

= 5 × 100,000

= 500,000
