**A****ns: **Weight of each tablet = 50 mg

Weight of box containing 5,00,000 tablets = 5,00,000 Ã— 50 mg.

= 2,50,00,000 mg

= 2,50,00,000 mg/1000 = 25000 g

= 25000 g/1000 = 25 kg**Ques 3: Population of Shivaji park was 2,35,471 in the year 2002. In the year 2012 it was found to be increased by 72,958. What was the population of the city in 2012?****Ans: **Population of Shivaji park in the year 2002 = 2,35,471

Increase in the population in the year 2012 = 72,958

Total population of the city in the year 2012 = 2,35,471 + 72,958 = 3,08,429**Ques 4: The town newspaper is published every day. One copy has 12 pages. Every day 12,000 copies are printed. How many total pages are printed every day?****Ans: **Number of pages in each copy = 12

Number of pages in 12,000 copies = 12,000 Ã— 12 = 1,44,000

Therefore, number of pages printed every day = 1,44,000**Ques 5: Starting from the greatest 5-digit number, write the previous five numbers in descending order.****Ans: **The largest 5-digit number is 99999.

The previous five numbers starting with 99999 in descending order are:

99999, 99998, 99997, 99996, 99995**Ques 6: Write 527864 using commas in Indian as well as International System of Numeration.****Ans: **The given number is 527864

Indian system of numeration = 5,27,864

International system of numeration = 527,864**Ques 7: In Mumbai, the number of bicycles sold in the year 2011-2012 was 7,43,000. In the year 2012-2013, the number of bicycles sold was 8,00,100. In which year, more bicycles were sold and by how many?****Ans: **The number of bicycles sold in the year 2011-2012 = 7,43,000

The number of bicycles sold in the year 2012-2013 = 8,00,100

We observe that 8,00,100 > 7,43,000

That is, in the year 2012-2013, more bicycles were sold by (8,00,100 â€“ 7,43,000) = 57,100**Ques 8: Starting from the smallest 8-digit number, write the next five numbers in ascending order.****Ans: **The smallest 8-digit number is 1,00,00,000.

The next five numbers in the ascending order are 10000000, 10000001, 10000002, 10000003, 10000004**Ques 9: Write 8945673 using commas in Indian as well as International System of Numeration.****Ans: **The given number is 8945673

Indian system of numeration = 89,45,673

International system of numeration = 8,945,673**Ques 10: The number of sheets of paper available for making notebooks is 25,000. Each sheet makes 12 pages of a notebook. Each notebook contains 300 pages. How many notebooks can be made from the paper available?**

**A****ns: **Number of sheets of paper available = 2,5000

Number of pages can be made with 1 sheet of paper = 12

Number of pages can be made with 2,5000 sheets of paper = 2,5000 Ã— 12 = 3,00,000

Number of pages in each notebook = 300

Number of notebooks that can be prepared with the paper available = 3,00,000/300

= 1000 notebooks**Ques 11: Sunny is a famous cricket player. He has so far scored 7,280 runs in test matches. He wishes to complete 10,000 runs. How many more runs does he need?****Ans:** Number of runs scored so far = 7,280

Number of runs he wish to score = 10,000

Number of runs he need to score = 10,000 â€“ 7,280 = 2,720**Ques 12: In an election, the successful candidate registered 6,72,500 votes and his nearest rival secured 4,78,500 votes. By what margin did the successful candidate win the election?****Ans: **Number of votes registered by the successful candidate = 6,72,500

Number of votes registered by the rival (opponent) = 4,78,500

successful candidate won the election by a margin of

6,72,500 â€“ 4,78,500 = 1,94,000 votes**Ques 13: The distance between the school and the house of a student is 1 km 875 m. Every day she walks both ways. Find the total distance covered by her in 15 days.****Ans: **Distance between the school and the house = 1 km 875 m

= 1000 m + 875 m

= 1,875 m.

Distance travelled by the student both ways, every day = 1,875 m Ã— 2 = 3,750 m

Distance travelled by the student in 15 days = 3,750 m Ã— 15

= 56,250 m

= 56 km 250 m**Ques 14: Medicine is packed in boxes, each weighing 5 kg 200 g. How many such boxes can be loaded in a van which cannot carry beyond 260 kg?****Ans: **Weight of each box = 5 kg 200 g = 5 Ã— 1000 g + 200 g

= 5000 g + 200 g = 5200 g

Maximum weight that can be loaded in a van = 260 kg = 260 Ã— 1000 g = 260000 g

No. of boxes that can be loaded in the van = 260000/5200 = 50 boxes**Ques 15: A student multiplied 1234 by 32 instead of multiplying by 23. By how much was his answer greater than the correct answer?****Ans: **The student did the problem as 1234 Ã— 32 (incorrect), instead of 1234 Ã— 23 (correct) Difference in the answers :

(1234 Ã— 32) â€“ (1234 Ã— 23)

= 1234 Ã— (32 â€“ 23)

= 1234 Ã— 9

= 11,106
