Question

Pratap correctly remembers that his
mother's birthday is before twenty third of
April but after Nineteenth of April, whereas
his sister correctly remembers that their
mother's birthday is not on or after twenty
second of April. On which day in April is
definitely their mother's birthday?​

Answer 1

Answer:

20 or 21st

Step-by-step explanation:

According to pratap

before 23rd April but after 19th (case 1)

so possible dates = 20,21,22

according to his sister, birthday is not on or after 22nd (case 2)

so when we consider both these cases birthday can be on 20th or 21st
