Question : If electric resistance is to be decreased, then the number of resistances should be connected in_________
Option 1: Series
Option 2: Parallel
Option 3: Mixed arrangement
Option 4: None of these

Question : The sides of a triangle are in the ratio $\frac{1}{3}: \frac{1}{5}: \frac{1}{6}$. If the perimeter is 147 cm, then the length of the smallest side is_____.
Option 1: 12 cm
Option 2: 25 cm
Option 3: 30 cm
Option 4: 35 cm
