An inheritance amounting to Php 14, 250, 000 is to be distributed to Don Alfonso's three sons with the ratio 7:3:5. How much will each son receive?

Sagot :

First son: 7x
Second son: 3x
Third son:  5x

Sum of the inheritance: Php 14,250,000

Equation:
7x + 3x + 5x = 14 250 000
15x = 14 250 000
15x/15 = 14 250 000
x = 950 000

Amount of inheritance each will receive: 
First son:  7 (950 000) = Php 6 650 000
Second son: 3 (950 000) =  Php 2,850 000
Third son: 5 (950 000) =  Php 4 750 000

Check:
Php 6 650 000 + Php 2 850 000 + Php 4 750 000 = Php 14 250 000
