29. Rounding to the nearest 10,000 is more sensible because this rounding gives a closer estimate.
389,250 rounded to nearest ten thousands is 390,000
201,780 rounded to nearest ten thousands is 200,000
Estimated difference = 390,000 − 200,000 = 190,000.
30. a) After rounding to the nearest 10,000
Population of City A = 130,000
Population of City B = 130,000
b) After rounding to the nearest 10,000, both cities appear to have the same population, 130,000.
c) After rounding to the nearest 100,000: Population of City A = 100,000; Population of City B = 100,000.
d) Yes, the population of both the cities is about 130,000 when rounded to the nearest 10,000 because City A (128,450) is only slightly below 130,000 and City B (130,025) is just above it. Since both are close to 130,000, rounding makes their populations appear the same.
31. a) Rounded to the nearest ₹10,000:
TV: ₹74,590 ₹70,000
Laptop: ₹76,410 ₹80,000
Phone: ₹49,499 ₹50,000
b) The banner says “All items under ₹75,000". Based on the rounded prices, only the TV (₹70,000) and Phone (₹50,000) can be advertised under this offer.
c) Rounded to the nearest ₹1,000:
TV: ₹74,590 ₹75,000
Laptop: ₹76,410 ₹76,000
Phone: ₹49,499 ₹49,000
d) After rounding to the nearest ₹1,000, the TV changes to ₹75,000, which is not under ₹75,000, while the Phone remains below ₹75,000.
So, the answer changes — now only the Phone can be advertised as under ₹75,000.
32 .a) Rounded off to the nearest 1,000 m:
Length of Road A = 149,000 m
Length of Road B = 151,000 m
The rounded lengths of the roads are different.
b) Rounded off to the nearest 10,000 m:
Length of Road A = 150,000 m
Length of Road B = 150,000 m
The rounded lengths of the roads are the same.
c) Rounding to the nearest 1,000 m gives a clearer comparison because it shows that Road B is slightly longer than Road A. Rounding to the nearest 10,000 m makes both roads appear equal in length, which is less accurate for comparison. Page 12
33. a) City population: 406,090 Usually rounded to the nearest 100,000
Populations are usually expressed in lakhs or rounded to the nearest one lakh. Rounded value = 400,000.
b) A bill amount of ₹19,410 Usually rounded to the nearest 10
Receipts and bills are usually accurate up to the nearest ten rupees. Rounded value = ₹19,410.
c) A road length of 151,480 m Usually rounded to the nearest 1,000
Road lengths are usually given to the nearest kilometre (1,000 m). Rounded value = 151,000 m.
d) A price tag of ₹74,590 Usually rounded to the nearest 1,000
Prices of expensive items are usually displayed rounded to the nearest thousand. Rounded value = ₹75,000.

11. Sample answer:
Yes, There is a mistake in the answer in the thousands place. The mistake is that when 1 thousand was borrowed from 4 thousands and regrouped into hundreds, 3 thousands should have been left behind. But the student kept 4 thousands instead of 3, which made the thousands place wrong in the answer.
The correct answer is 58,324

If you add 24,750 to 139,900, you get 164,650.
To check, do the opposite: 164,650 − 24,750. If it gives back 139,900, the answer is correct.
2. Subtraction and addition undo each other.
If you subtract 121,980 from 268,451, you get 146,471.

21. 1. Nearest 1,000 m:
Road A ≈ 149,000 m
Road B ≈ 151,000 m
Road B is longer by about 2,000 m.
2. Nearest 10,000 m:
Road A ≈ 150,000 m
Road B ≈ 150,000 m
They look the same after rounding to this place.
Rounding to the nearest 1,000 m is more informative because it shows the difference between the lengths of the two roads.

Horizontally symmetrical: B, C, D, E, H, I, K, O, X
Both vertical and horizontal symmetry: H, I, O, X 10.
1 m = 100 cm = 1000 mm 1 km = 1000 m = 10,000 dm = = 100,000 cm = 1,000,000 mm Page 91 4.
12. The STOP sign is an octagon (8 sides). It has 8 lines of symmetry (each line passes through opposite vertices or midpoints of opposite sides).
Road signs often use symmetrical shapes because they are easy to recognize and look the same from multiple directions.

40. One possible method:
1. Fill the 5 L jug completely.
2. Pour water from the 5 L jug into the 3 L jug until it is full.
3. The 5 L jug now has 2 L left.
4. Empty the 3 L jug. Pour the 2 L from the 5 L jug into it.
5. Fill the 5 L jug again and pour into the 3 L jug until it is full.
Now there are 4 L of water left in the 5 L jug.
41. Way 1: Use the 1-litre flask seven times (7 × 1 L = 7 L).
Way 2: Use the 500-millilitre flask fourteen times (14 × 500 mL = 7000 mL = 7 L).
