Solutions :-


Given :
Lalita can complete 100 question in 3 hours.

Find the time to complete 1 question :-

By unitary method,
100 questions = 3 hours or
1 questions = 3/100 = 0.03 hours



Find the time to complete 25 questions :-

By unitary method,
1 questions = 0.03 hours
25 questions = 0.03 × 25 = 0.75 hours


Now, we know
1 hours = 60 minutes
0.75 hours = 60 × 0.75 = 45 minutes


Hence,
she will take 45 minutes to complete 25 questions .
