[2 MARKS]

Answer:
:
Each Option: 1 Mark
(a)

2 h r s = 60 \times 2 = 120

minutes (1 hr = 60 minute)
Ratio of 20 minutes to 2 hrs = 20:120 =1:6
[ Remember that for taking ratio unit of both quantitiesshould be same ]
(b)

5 : 4 :: 125 : x \Rightarrow \frac{5}{4} = \frac{125}{x}

\Rightarrow \frac{5}{4} = \frac{125}{x}

\Rightarrow \frac{4}{5} = \frac{x}{125}

\Rightarrow x = \frac{125 \times 4}{5} = 25 \times 4

\Rightarrow x = 100
