Question

What time should the $IV$ clock show if all the clocks follow the same pattern?

• A. $1:00$
• B. $1:20$
• C. $1:40$
• D. $2:00$

Answer 1

Answer: (B)

$1:20$

First clock shows time $11:20$

Second clock shows time $11:40$

Third clock shows time $12:20$

Fifth clock shows time $2:40$

Sixth clock shows time $4:20$

So, the time gap between first three adjacent clocks is $20$ and $40$ minutes

Also, the time gap between last two adjacent clocks is $100$

So, they follow the pattern of difference as $20,40,60,80,1000$

If we add $60$ minutes to the third clock we get the time as $12:20+60min=1:20$

Thus, the time in (IV) clock is $1:20$.
