Q20. Pebbles puzzle:
Let number = N
N mod 3 = 1, N mod 2 = 1, N mod 5 = 1, N mod 7 = 0
LCM of 3,2,5 = 30, so N = 30k + 1, divisible by 7
Try k = 1 → 31, k=2 → 61, k=3 → 91 (91 ÷ 7 = 13)
N = 91 pebbles (less than 100)
SECTION-C (4 × 3 = 12 Marks)
Q21. Machine value decreases by 8% every year. Present value = Rs.60000. Value after 2 years:
After 1st year = 60000 × (1 - 0.08) = 55200
After 2nd year = 55200 × 0.92 = Rs.50784
Q22. 12 tankers → 15 days. If 4 stop, remaining = 8 tankers:
12 × 15 = 8 × D → D = (12×15)/8 = 22.5 days
Q23. Identity (a + b)(a - b) = a² - b²
(a) Identity: (a + b)(a - b) = a² - b²
(b) 86 × 74 = (80 + 6)(80 - 6)
(c) = 80² - 6² = 6400 - 36 = 6364
OR
(a + b)² = a² + 2ab + b²
Side = 65 m → Area = 65² = 4225 m²
Q24. Truck travels 360 km in 6 hours:
(a) Speed = 360/6 = 60 km/h
(b) Distance in 11 hours = 60 × 11 = 660 km
OR
Oxen ploughs 1 acre in 6 hours → 20 acres = 120 hours
Tractor is 4 times faster → Time = 120/4 = 30 hours
SECTION-D (3 × 5 = 15 Marks)
Q25. Length = (x + 8), Breadth = (x - 2)
Area = (x + 8)(x - 2) = x² + 6x - 16
New length = (x + 9), new breadth = (x - 1)
New area = (x + 9)(x - 1) = x² + 8x - 9
Increase = (x² + 8x - 9) - (x² + 6x - 16) = 2x + 7
Q26. Parallel sides ratio = 3:5, height = 12 cm, area = 192 cm²
(a) Let sides = 3k and 5k
Area = ½ × (3k + 5k) × 12 = 192
½ × 8k × 12 = 192 → 48k = 192 → k = 4
Sides = 12 cm and 20 cm(b) New sides = 16 cm and 24 cm
New area = ½ × (16 + 24) × 12 = ½ × 40 × 12 = 240 cm²
Q27. Investment = Rs.50,000, 2 years, 10% rate
(a) Simple Interest = 50000 × 2 × 0.10 = Rs.10000
(b) Compound Interest = 50000 × (1.1)² - 50000 = 60500 - 50000 = Rs.10500
(c) Difference = 10500 - 10000 = Rs.500
OR
Cost = 100 × 40 = 4000
40 kg at 10% profit → SP = 40 × 40 × 1.1 = 1760
35 kg at 20% loss → SP = 35 × 40 × 0.8 = 1120
Remaining 25 kg at 25% profit → SP = 25 × 40 × 1.25 = 1250
Total SP = 1760 + 1120 + 1250 = 4130
Profit = 4130 - 4000 = 130
Profit % = (130/4000) × 100 = 3.25%
SECTION-E (CBQ) (2 × 4 = 8 Marks)
Q28. Triangle and parallelogram on same base 18 cm, area of parallelogram = 288 cm²
(a) Height of parallelogram = Area/Base = 288/18 = 16 cm
(b) Area of triangle = ½ × base × height = ½ × 18 × 16 = 144 cm²
(c) Height of triangle = same as parallelogram = 16 cm
(d) Observation: Heights are equal (same base and between same parallels)
Q29. Muesli ingredients in 500g:
(a) Almonds = 12.5% of 500 = 62.5g, Raisins = 15% of 500 = 75g → Total = 137.5g
(b) Honey in 1kg = 12.5% of 1000 = 125g
(c) Rolled oats = 40% of 500 = 200g, Raisins = 75g → Difference = 200 - 75 = 125g more oats
(d) Missing Wheat Flakes % = 100 - (40 + 15 + 12.5 + 12.5) = 100 - 80 = 20%
