Answer:

Step-by-step explanation:
Let X be the time for only a small drain, the work completed would be unity.
The small drain has been open for a total of 11 hours, one hour next to the large one, and 10 hours alone.
We have that large drainage can accomplish this in 2 hours.
We have the following system:
1/2 + 11 / x = 1
solving, we have:
11 / x = 1 - 1/2
11 / x = 1/2
x = 11 * 2
x = 22
I mean it would take a total of 22 hours for the small drain alone
When you are 10 years ,your sister will be 10/2 = 5 years
10 - 5 = 5
Your sister is 5 years younger to you
After 90 years your age will be 100 years.
After 90 years your sister's age will be 5+90 = 95 years
Correct option A
Hope This Helps You!
