Question 3

Which number am I?
I am a two-digit number, help of the following clues.
(а) I am greater than 8.
(b) I am not a multiple of 4.
(c) I am a multiple of 9.
(d) I am an odd number.
(e) I am not a multiple of 11.
(f) I am less than 50.
(g) My ones digit is even.
(h) My tens digit is odd.

Accepted Answer

Step 1: All 2-digit multiples of 9 less than 50 are: 18, 27, 36, 45Step 2: Remove multiples of 4. 36 is a multiple of 4. So, remove it.Remaining number are: 18, 27, 45Step 3: Keep only odd numbers. Since, 18 is even. So, remove it.Then the remaining numbers are: 27 and 45.Step 4: Remove multiples of 11: 22, 33, 44, 55,… Here, neither 27 nor 45 is a multiple of 11. So, both the numbers remain.Step 5: But the numbers are less than 50 So, both 27 and 45 are fit with the given clue.Step 6: Ones digit is even. But, in 27, ones digit is 7 (odd) and in 45, ones digit is 5 (odd). Here, is a contradiction. As both the numbers 27 and 45 are odd. [as per the clue (d)].Hence, no 2-digit number is possible that satisfies all the given clues.Did you use all the clues to find the number? Which clues did not help you in find the number?Solution:Except clue (a) and (b), rest of all the clues were helpful in trying to guess the number.If we ignore clue (d), the number should be either 18 or 36.And if we ignore clues (g) and (h), and consider clues (e) then the number should be either 27 or 45.

Question 4

Make your own numbers.
Choose any two numbers and one operation from the grid. Try to make all the numbers between 0 and 20. For example 2 can be formed as 4 – 2. Could you make all the numbers?

Accepted Answer

36 – 25 =11, (Answer may vary) or 36 ÷ 4 = 9, etc.Which numbers could you not make? Is it possible to make these numbers using three numbers? You can use two operations, if needed. Which numbers between 0-20 can you get in more than one way?Solution:Do it yourself.NCERT Textbook Pages 72-74Order of Numbers in MultiplicationDaljeet Kaur runs a milk processing unit.

Solve the following problems:
(a) A movie theatre has 8 rows of seats, and each row has 12 seats. If half the seats are filled, how many people are watching the movie? If 3 more rows get filled, how many total people will be there?

Accepted Answer

Number of rows of seats in the movie theatre = 8Number of seats in each row = 12Since, half seats are filled, that is 4 rows out of 8 are filled.So, number of people who watched the movie = 4 × 12Thus, 48 people watched the movie.Now, 3 more rows get filled.Therefore, number of people who will watch the movie = 7 × 12Thus, 84 people will be there, if 3 more rows get filled.(b) In a test match between India and West Indies, the Indian team hit twenty- four 4s and eighteen 6s across the two innings. How many runs were scored in 4s and 6s each? 234 runs were made by running between the wickets. If 23 runs were extras, how many runs were scored by Indian team in the two innings?Solution:In the test match, number of 4s hit by Indian team = 24Therefore, runs scored by Indian team by hitting 4s = 24 × 4 = 96 runs 96 runsIn the test match, number of 6s hit by Indian team = 18Therefore, runs scored by Indian team by hitting 6s = 18 × 6 = 108 runsRuns scored by running between the wickets = 234 runsRuns scored by extras = 23 runsTherefore, total runs scored by the Indian team in two innings = 96 + 108 + 234 + 23 = 461 runs(c) Anjali buys 15 bulbs and 12 tube lights from Sudha Electricals.

Each bag costs ?350. How much money did he earn by selling rice bags?Solution:The cost of each rice bag = ₹ 350Since, a shopkeeper sold 28 bags of rice. 350 (300 + 50 + 0)Therefore, total cost of 28 bags of rice = 350 × 28 = ₹ 9800Thus, the shopkeeper earned ₹ 9800 by selling 28 bags of rice.(e) A school library has 86 shelves and each shelf has 162 books.
