Answer: (c) Day after tomorrow
Explanation
Finding the day
Given: the day before yesterday was Tuesday.
We need to say when Saturday will be.
How to think: first fix today.
Then count forward to Saturday.
| Day | Name |
|---|---|
| Day before yesterday | Tuesday |
| Yesterday | Wednesday |
| Today | Thursday |
| Tomorrow | Friday |
| Day after tomorrow | Saturday |
| Two days after tomorrow | Sunday |
Today is Thursday.
Saturday is two days after Thursday.
Two days after today is the day after tomorrow.
The options checked:
| Option | Day it stands for |
|---|---|
| Today | Thursday |
| Tomorrow | Friday |
| Day after tomorrow | Saturday |
| Two days after tomorrow | Sunday |
Answer: (c) Day after tomorrow.
Why each option is right or wrong
- (a) Incorrect. Today is Thursday.
- (b) Incorrect. Tomorrow is Friday.
- (c) CORRECT. Today is Thursday, so Saturday is the day after tomorrow.
- (d) Incorrect. Two days after tomorrow is Sunday.
Key point
Day before yesterday = today minus 2. Tuesday + 2 = Thursday (today). Saturday = today + 2 = day after tomorrow.
Remember
Day before yesterday is two days back; day after tomorrow is two days ahead.
Common mistakes
- Taking yesterday as Tuesday and getting today as Wednesday.
- Mixing up the day after tomorrow with two days after tomorrow.
- Counting Tuesday itself as day one while moving forward.
Exam tip
Write the days in a row from Tuesday and mark today. It takes five seconds and avoids a slip.
