Q: 1 If the time is now 4 O’clock, what will be the time after 101 hours from now ? 

(1) 9 O’clock (2) 8 O’clock (3) 5 O’clock (4) 4 O’clock

Answer: (1)

To find the time after 101 hours from 4 o’clock, we can use the modulo operation with respect to 12 (since it’s a 12-hour clock).

1. First, calculate the remainder when 101 is divided by 12:
   
   Quotient is 8 and Remainder is 5
2. Now add this remainder to the current time: 
   
   i.e. 4+5 = 9
   
   

   Thus, 101 hours from 4 o’clock will be 9 o’clock.

   The correct answer is (1) 9 O’clock.
