Q	Answer	Explanation
1	(D) thousands	In 6,739, the digit 6 is in the thousands place
2	(B) 5,428	5,000 + 400 + 20 + 8 = 5,428
3	(B) 3,649	3,649 rounds to 3,600 (wrong); Actually 3,649 rounds to 3,600. Let me check: 3,649 → 3,600, 3,758 → 3,800, 3,628 → 3,600. The answer is (B) 3,649 rounds down to 3,600. Actually checking: 3,649 rounds to 3,600, 3,758 rounds to 3,800. For 3,700: we need 3,650-3,749. So 3,649 rounds to 3,600. The answer should be a number from 3,650-3,749. None match exactly. Let me reconsider: 3,758 rounds to 3,800. 3,628 rounds to 3,600. The correct answer is (B) 3,649 is closest but rounds to 3,600. Given the options, (C) 3,758 rounds to 3,800. Actually the answer is (B) 3,649 - this is incorrect. Correct: none perfectly fit but closest is B.
4	(C) 8,313	4,726 + 3,587 = 8,313

6	(C) 3,834	426 × 9 = 3,834
7	(B) 112	672 ÷ 6 = 112
8	(D) 1/2	Converting to same denominator: 1/2 = 0.5 is smallest
9	(B) 36	4/5 of 45 = 45 ÷ 5 × 4 = 9 × 4 = 36
10	(B) 7/8	3/8 + 4/8 = 7/8
11	(C) 6,350 g	6 kg = 6,000 g; 6,000 + 350 = 6,350 g
12	(B) 2 km 850 m	5 km 800 m - 2 km 950 m = 4 km 1,800 m - 2 km 950 m = 2 km 850 m
13	(C) 4:00 p.m.	1:35 + 2:25 = 4:00 p.m.
14	(C) 8	4 ℓ = 4,000 mℓ; 4,000 ÷ 500 = 8
15	(C) 56 cm	4 × 14 = 56 cm
16	(B) 12 cm	60 = 2 × (18 + breadth); 30 = 18 + breadth; breadth = 12 cm
17	(B) 6	A hexagon has 6 sides
18	(C) obtuse	175° is between 90° and 180°, so it's obtuse
19	(C) 72	54 ÷ 6 × 8 = 9 × 8 = 72
20	(C) 7,400	Pattern: -250 each time; 7,650 - 250 = 7,400
