Answer: The widow got Rs 500.05 and the son got Rs 1400.14
Explanation:
Starting from Rs 4000.40, to obtain how much did the widow get we should just multiply the amount by 0.125:
![Widow = 4000.40 * 0.125 = 500.05](https://img.qammunity.org/2020/formulas/mathematics/middle-school/g2yk8zir9qklkcu8a841aebqybmpq2fw18.png)
Then, the son gets 0.4 of what is left, we must first substract the amount the wife got from the initial amount and then multiply it by 0.4:
![Son = (4000.40 - 500.05)*0.4=(3500.35)*0.4=1400.14](https://img.qammunity.org/2020/formulas/mathematics/middle-school/2hzkrh5h3jxqincrkso5cpogrvuu2xntjz.png)
