उत्तर
5m = 60
m = 12 is a solution to the given equation because for m = 12,
5m = 5 × 12 = 60 and hence, the equation is satisfied.
m = 10 is not a solution to the given equation because for m = 10,
5m = 5 × 10 = 50 and not 60
m = 5 is not a solution to the given equation because for m = 5,
5m = 5 × 5 = 25 and not 60
m = 15 is not a solution to the given equation because for m = 15,
5m = 5 × 15 = 75 and not 60
