Question 2.
A box of medicine contains 3,00,000 tablets each weighing 15mg. What is the total weight of all the tablets in the box in grams and in kilograms?
Answer:
Weight of a tablet = 15 mg
Weight of 3,00,000 tablets = 300000 × 15
Weight of one box of tablets = 45,00,000 mg
we know 1000 mg = 1 gram
To convert mg into grams we have to divide grams by 1000 mg = 45,00,000 ÷ 1000
Weight of one box of tablets in grams = 4500 grams.
We know 1000g = 1kg
To convert ‘g’ into kilograms we have to divide kilograms by 1000g = \(\frac{4500}{1000}\) = 4.5 kg
Question 3.
Damodhar wants to buy onions in Kurnool market. Each onion bag weighs 45 kg. He loaded 326 onion bags with 45kg in a lorry. Find the total weight of onions in kilograms and quintals.
Answer:
Weight of one bag onions = 45 kg
Weight of 326 bag onions = 326 × 45 = 14,670 kg
We know, 100 kg = 1 quintal.
To convert kgs into quintal we have to divide kgs by 100
= 14670 ÷ 100 = 146.7 quintals.
Question 4.
The population of 4 South Indian States according to 2011 Census:

Answer:
Number of runs wishes to complete = 50,000

Number of runs needed = 50,000 – 28,754 = 21,246 runs
Question 6.
In an election, the successful candidate registered 1,32,356 votes and his nearest rival secured 42,246 votes. Find the majority of successful candidate.
Answer:
Number of votes secured by the winner = 1,32,356
Number of votes secured by the rival = 42,246
Number of more votes secured by the winner = 1,32,356 – 42,246 = 90,110
Majority of the winner = 90,110 votes.
Question 7.
Write the greatest and smallest six digit numbers formed by all the digits 6, 4, 0, 8, 7, 9 and find the sum and difference of those numbers.
Answer:
Given digits are 6, 4, 0, 8, 7, 9
The greatest number formed by the digits = 9,87,640
The smallest number formed by the digits = 4,06,789
Sum of the numbers = 9,87,640 + 4,06,789 = 13,94,429
Difference between numbers = 987640 – 406789 = 580851
Question 8.
Haritha has Rs. 1,00,000 with her. She placed an order for purchasing 124 ceiling fans at Rs. 726 each. How much money will remain with her after the purchase?
