Q1. If your cartoon starts at 3 o’clock and the minute hand is on 6, what time is it?

(a) 3:00
(b) 3:15
(c) 3:30
(d) 3:45

Ans: (c) 3:30

When the minute hand is on 6, it’s 30 minutes past the hour (half past). With the hour hand on 3, it’s half past three, or 3:30.

Q2. What time is it when the hour hand is on 10 and the minute hand is on 3?

(a) 10:00
(b) 10:15
(c) 10:30
(d) 10:45

Ans: (b) 10:15

The minute hand on 3 means 15 minutes past the hour (quarter past), as each number is 5 minutes and 3 × 5 = 15. With the hour hand on 10, it’s 10:15.

Q3. You finish lunch at 1:00. If it took you half an hour, what time did you start?

(a) 12:00
(b) 12:30
(c) 12:45
(d) 1:30

Ans: (b) 12:30

Half an hour is 30 minutes. Subtract 30 minutes from 1:00: 1:00 - 0:30 = 12:30.

Q4. If the minute hand is on 9 and the hour hand is between 6 and 7, what time is it?

(a) 6:15
(b) 6:30
(c) 6:45
(d) 7:00

Ans: (c) 6:45

The minute hand on 9 means 45 minutes past (9 × 5 = 45). The hour hand between 6 and 7 indicates it’s after 6 but before 7, so it’s 6:45.

Q5. What time is it when the hour hand is on 5 and the minute hand is on 12?

(a) 5:15
(b) 5:00
(c) 5:30
(d) 5:45

Ans: (b) 5:00

 When the minute hand is on 12, it’s 0 minutes past the hour. The hour hand on 5 means it’s 5 o’clock, or 5:00.

Q6. If the minute hand is on 6 and the hour hand is on 2, what time is it?

(a) 2:00
(b) 2:15
(c) 2:30
(d) 2:45

Ans: (c) 2:30

The minute hand on 6 means 30 minutes past the hour (half past). With the hour hand on 2, it’s half past two, or 2:30.

Q7. If the minute hand is on 9 and the hour hand is between 11 and 12, what time is it?

(a) 11:15
(b) 11:30
(c) 11:45
(d) 12:00

Ans: (c) 11:45

The minute hand on 9 means 45 minutes past (9 × 5 = 45). The hour hand between 11 and 12 indicates it’s after 11 but before 12, so it’s 11:45.

Q8. If the minute hand is on 7 and the hour hand is between 3 and 4, how many minutes past 3 is it?

(a) 25
(b) 30
(c) 35
(d) 40

Ans: (c) 35

The minute hand on 7 means 35 minutes past (7 × 5 = 35). The hour hand between 3 and 4 confirms it’s after 3, so it’s 35 minutes past 3 (3:35).

Q9. School starts at 8:00 and ends 4 hours later. What time does it end?

(a) 11:00
(b) 12:00
(c) 1:00
(d) 2:00

Ans: (b) 12:00

Add 4 hours to 8:00: 8 + 4 = 12, so school ends at 12:00. 

Q10. A shop opens on Monday, 1st April, and closes for 7 days. On what date and day does it reopen?

(a) Monday, 8th April
(b) Tuesday, 9th April
(c) Sunday, 7th April
(d) Wednesday, 10th April

Ans: (b) Tuesday, 9th April

Start with Monday, 1st April. Add 7 days (1 week):

• 2nd: Tuesday (1),
• 3rd: Wednesday (2),
• 4th: Thursday (3),
• 5th: Friday (4),
• 6th: Saturday (5),
• 7th: Sunday (6),
• 8th: Monday (7).
  It closes for 7 days, so reopens on the 8th day: Tuesday, 9th April (1st + 8 days), similar to practice question (iv).
