NCERT: Math-Magic Solutions for Class-3, Chapter-2: Fun with Numbers

From the given picture, note down the number of Imli seeds collected by Radhika, Gauri, Vicky, Indra, and Sunil. As shown in the table,

• From the table, 54 is the highest number of seeds collected by anyone. It is Indra who collected 54 seeds. So, Indra collected the most seeds.
• From the table, Sunil collected 38 seeds, and Vicky collected 42 seeds. So, Sunil will need 42 − 38 = 4 more seeds to be equal to Vicky. Therefore, Sunil will collect 4 more seeds to be equal to Vicky.
• From the table, Radhika has collected 24 seeds. If she gets 6 more seeds, then she will have 24 + 6 = 30 seeds. Therefore, if Radhika gets 6 more seeds, she will have 30 seeds.
• From the table, Gauri, Vicky and Indra each have collected more than 40 seeds. Therefore, three children have more than 40 seeds.
• From the table, Gauri has collected 47 seeds. To have 50 seeds, she will need 50 – 47 = 3 more seeds. Therefore, Gauri needs 3 more seeds to have 50.
• Two seeds more than 40 means, 40 + 2 = 42. From the table, Vicky has collected 42 seeds. Therefore, Sunil has 2 seeds less than 40 and Vicky has 2 seeds more than 40

Triple century = 3 × 100 = 300 300 −206 94 It will take 94 more runs to make a triple century.

After scoring 96 runs, Dhoni continues his batting, followed by a marvellous six. So, Dhoni scored, 96 + 6 = 102 runs. A century means 100. Since Dhoni scored 102 runs, he has completed his century. Hence, Dhoni has completed a century.

1. From the table, C.K. has scored 99 runs. A century means 100. So, he needs 100 – 99 = 1 run to complete his century. Therefore, C.K. needs 1 run to make a century.
2. From the table, A.P.J. has scored 128 runs, and V.V.S. has scored 127 runs. Also, A.S. has scored 100 runs, and C.K. has scored 99 runs. Therefore, A.P.J. and V.V.S. scored almost equal runs. A.S. and C.K. scored almost equal runs.
3. From the table, A.S. has scored exactly 100 runs. Therefore, A.S. scored a complete century, no less, no more.
4. From the table, 178 is the highest run that M.D. has scored.
5. Therefore, most runs scored by any batsman is 178.
6. From the table, A.P.J. has scored 128 runs, and V.V.S. has scored 127 runs. Also, A.S. has scored 100 runs, and C.K. has scored 99 runs. Therefore, A.P.J. and V.V.S. have a difference of just 1 run between them. A.S. and C.K. have a difference of just 1 run between them.
7. One and a half century means, 100 + 50 =150. So, 2 more than one and half century mean, 150 + 2 =152. From the table, K.S.P. has scored 152 runs. Therefore, K.S.P. scored 2 more than one and a half century.

• Counting in 50’s like this will never end as there is no limit to numbers. But counting in 50’ ends on 950 for three-digit numbers.
• There is no such biggest number to call out as there is no limit to numbers. But when counting in 50, 950 is the biggest number for three-digit numbers.

1. Bunny starts jumping from number 99 and jumps on every 5th box. Hence, Bunny’s tenth jump will be on the number 99 + (5 × 10) = 99 + 50 = 149
2. Tarru starts jumping from the number 106 and jumps on every 4th box. Hence, Tarru’s tenth jump will be on the number: 106 + (4 × 10) =106+40=146
3. Gabru starts jumping from the number 90 and jumps on every 7th box. Hence, Gabru’s tenth jump will be on the number: 90 + (7 × 10) =90+70=160
4. Observe Bunny’s and Gabru’s Jumps. Bunny’s Jumps:  Gabru’s Jumps:  So, Bunny and Gabru both jump on numbers 104, 139 and 174.

For the elephant:
The elephant will pay 420 rupees.
420 =4 × 100 + 2 ×10
So, the elephant will pay Rs. 420 as four Rs.100 notes and two Rs.10 notes.
For the rabbit:
143 =1×100 + 4 ×10 + 3 × 1
So, the rabbit will pay Rs.143 as one Rs.100 note, four Rs.10 notes and three Rs.1 coins.
For the monkey:
242 = 2 × 100 + 4 × 10 + 2 × 1
So, the monkey will pay Rs.242 as two Rs.100 notes, four Rs.10 notes and two Rs.1 coins.
For the deer:
55 = 5 × 10 + 5 × e
So, the deer will pay Rs. 55 as five Rs.10 notes and five Rs.1 coins.

Count the groups of 100s, 10s and 1s, add them as their place value. The correct answer is:

CExpand the given numbers in 100s, 10s and 1s.

The correct answer is:

28 stars. 100 + 100 + 100 + 100 +100 + 100 + 100 + 100 +100 + 100 = 900 +100 =1000 1000 is a four-digit number. After counting from the picture, we get that there are 18 + 10 + 10 = 38 stars in pocket.
