Question

1) Find the ratio of 3 min 54 sec to 2 min 6 sec.
2) Frame the linear equation in two variables for - "The sum of two numbers is 125 and their difference
is 30'.​

Answer 1

1) Convert time to seconds

3 min 54 sec = 3×60 + 54 = 234

2 min 6 sec = 2×60 + 6 = 126

ratio = 234:126 = 13:7

2) Let the two number be x and y

sum i.e x + y = 125

and difference x - y = 30
