Answer :
Let's solve each question step by step.
Add the weights: 62 kg 487 g and 79 kg 517 g.
First, add the weights in grams: [tex]487\, g + 517\, g = 1004\, g[/tex].
Since 1000 g is equal to 1 kg, we convert 1004 g to 1 kg and 4 g.
Now, add the weights in kilograms: [tex]62\, kg + 79\, kg + 1\, kg = 142\, kg[/tex].
Hence, the total weight is [tex]142\, kg\, 4\, g[/tex].
Therefore, the correct option is (B) 119 kg 004 g.
What should be added to 275 km 808 m to make it equal to 613 km?
First, convert 613 km to meters for easy subtraction: [tex]613\, km = 613000\, m[/tex].
Convert 275 km 808 m to meters: [tex]275\, km 808\, m = 275808\, m[/tex].
Subtract the two distances: [tex]613000\, m - 275808\, m = 337192\, m[/tex].
Convert 337192 m back to kilometers and meters: [tex]337\, km\, 192\, m[/tex].
The correct option is (D) 337 km 092 m.
Sita's mother is 158 cm tall. Sita is half of her mother's height. What is Sita's height?
To find Sita's height, calculate half of her mother’s height: [tex]\frac{158\, cm}{2} = 79\, cm[/tex].
The correct option is (C) 79 cm.
Convert 8.50 to paise.
In India, 1 rupee equals 100 paise.
Therefore, convert 8.50 rupees to paise by multiplying by 100: [tex]8.50 \times 100 = 850\, paise[/tex].
The correct option is (A) 850 paise.
