Question 11 : Look at the number patterns. Write the missing numbers.

Answer :
a) Observe the pattern, the difference between the numbers is 100 and numbers are increasing. So, the missing numbers will be 3 300 +100 = 400, 400 +100 = 500, 600 +100 =700 Therefore, the correct answer is:
100, 200, 300, 400, 500, 600, 700
b) Observe the pattern, the difference between the numbers is 900 −800 =100 and numbers are decreasing. So, the missing numbers will be
700 −100 = 600, 600 – 100 = 500, 400 − 100 = 300 Hence, the correct answer is:

c) Observe the pattern, the difference between the numbers is 100−50 = 50 and numbers are increasing. So, the missing numbers will be
200 + 50 = 250, 250 + 50 = 300, 300 + 50 = 350, 350 + 50 = 400
Hence, the correct answer is:
50, 100, 150, 200, 250, 300, 350, 400
d) Observe the pattern, the difference between the numbers is 100 −50 = 50 and numbers are decreasing. So, the missing numbers will be
200 − 50 = 150, 150 − 50 =100, 100 − 50 = 50 Hence, the correct answer is:

e) Observe the pattern, the difference between the numbers is 35−25 = 10 and numbers are increasing. So, the missing numbers will be:
25 − 10 = 15, 45 + 10 = 55, 55 + 10 = 65
Hence, the correct answer is:

f) Observe the pattern, the difference between the numbers is 280−260 =20 and numbers are decreasing. So, the missing numbers will be
240 − 20 =220, 220 − 20 = 200, 200 – 20 =180, 180 – 20 = 160 Hence, correct answer is:
280, 260 ,240 ,220 , 200 , 180, 160
g) Observe the pattern, the difference between the numbers is 150 – 125 = 25 and numbers are increasing. So, the missing numbers will be
200 + 25 = 225, 250 + 25 = 275, 275 + 25 = 300 Hence, the correct answer is:
125, 150, 175, 200, 225, 250, 275, 300

Since 44 – 18 = 26,
sugar is Rs 26 costlier than salt.

b) Did she sell more red sweaters than blue sweaters in 2 days?
c) How many red and grey sweaters did she sell on the first day? Tick(✔) the right answer. more than 120 or less than 120 ?
d) How many sweaters in all did she sell on the second day. Tick(✔) the right answer. more than 140 or less than 140 ?

Answer :
a) From the given chart it is clear that Chanchal has sold a total of (74 + 89) grey sweaters in 2 days.
74 + 89 = 163
So, she has sold 163 grey sweaters in 2 days.
b) Chanchal sells 38 and 40 red sweaters in 2 days So, total number of red sweaters are (38+40)
38 + 40 = 78
So, she has sold 78 red sweaters.
So, total number of blue sweaters are (66 + 23)
66 + 23 = 89
Chanchal has sold 78 red sweaters and 89 blue sweaters in 2 days. Since 89 > 78, she has sold more blue sweaters than the red ones. c) Chanchal has sold 38 red sweaters and 74 grey sweaters on the 1st day.
38 + 74 = 112
Since 112 < 120, the answer is less than 120 .
d) Chanchal sold 40 red sweaters, 23 blue sweaters and 89 grey sweaters on the 2nd day. 40 + 23 + 89=152 Since 152> 140, the answer is more than 140 .

Question 17 : Sangeeta went to the market with her grandpa.

Is Sangeeta right? Mark (  ) or (  ) in the box.
Can you find this without using paper and pencil?

Answer :
a) From the picture, ghee is Rs 127 and biscuits are Rs 25.
127 – 25 = 102
Ghee is Rs 102 rupees costlier than biscuits. 
b) From the picture, price of oil is Rs 70 and the price of ghee is Rs 127. Total price of oil and ghee is
70 + 127 = 197
Since 197 < 200, price of oil and ghee altogether is more than Rs 200.
 c) From the picture , price of ghee is Rs 127 and the price of 10 kg rice is Rs 150. So, the total price of oil and ghee is
127 + 150=277
Hence, the price of ghee and 10 kg rice is less than Rs 300 
d) The cost of oil is Rs 70 and the cost of one packet of biscuits is
Rs 25. 70 – 25=45
So, oil cost Rs 45 more than a packet of biscuit. Oil costs Rs 40 more than a pack of biscuits. 

Answer : The correct answer is:

Question 20 : How many horses in all did the king have?

Answer : The king has total
3 + 3 + 3 + 3 +3 + 3 +3 + 3
= 6 +3 +3 +3 +3 +3 + 3
= 9 +3 +3 +3 +3 + 3
= 12+3 +3 +3 + 3
= 15 +3 +3 + 3
= 18 +3 + 3
= 21 + 3
= 24 horses
So, the king has 24 horses in total.

Question 21 : How many horses are there now?

Answer : After the visitor left his 4 horses, There are total
2 + 5 + 2 + 5 + 2 + 5 + 2 + 5
= 7 +2 + 5 + 2 + 5 + 2 + 5
= 9 + 5 + 2 + 5 + 2 +5
= 14 + 2 + 5 + 2 +5
= 16 + 5 + 2 +5
= 21 + 2 +5
= 23 + 5
= 28 horses
So, now there are 28 horses in total.

Question 22 : How many horses are left now?
How many of the king's horses were taken away?

Answer : The visitor took away some of the king’s horses along with his own horses. Now, there are:
4 + 1 + 4 + 1 + 4 +1 + 4 +1
= 5+ 4 + 1+ 4 +1 + 4 +1
= 9 + 1+ 4 +1 + 4 +1
=10 + 4 +1 + 4 +1
=14 +1 + 4 +1
=15 +4 +1
=19 +1
=20
Therefore, there are 20 horses left in total. Initially the king had 24 horses in total and now he is left with 20 horses.
So, the total number of king’s horses that were taken away is 24 – 20 = 4 horses.

Question 23 : What numbers are we? If you add us both you get 100. The difference between us is also 100.

Answer : If zero is added with any number then the number remains the same. Similarly, if zero is subtracted from any number then also the number remains the same.
So, if the total of two numbers is 100 and the difference is also 100, then clearly the numbers are 0 and 100.
