Let x kg cement added. New cement = 10+x, sand=30.
Ratio 30/(10+x) = 5/2 → 60 = 50+5x → 5x=10 → x=2 kg.

Q27: Lotus stem tip 1 unit above water, bends to touch water 3 units away horizontally → depth?
✅ Answer: Let depth = d, stem length = d+1.
Pythagoras: (d+1)² = d² + 3² → d²+2d+1 = d²+9 → 2d=8 → d=4 units.
OR
(a) Scaled triple from (5,12,13): multiply by k=2 → (10,24,26), k=3 → (15,36,39).

Q6: Sum of first (n−1) odd numbers?
a) 3n b) n² c) n³ d) 4n
✅ Answer: b) n²
Explanation: Sum of first k odd numbers = k². Here k = n−1 → (n−1)². But options don’t match? Wait, they say first (n−1) odd numbers sum = (n−1)². But given options: n² is for first n odds. This seems mismatch. Likely answer:  if they meant first n−1 odds sum = (n−1)² not in options, so maybe misprint.

Q7: How many inches in 1 ft?
a) 142 b) 145 c) 144 d) 146
✅ Answer: None match — actually 1 ft = 12 inches. But maybe they meant in cm? 1 ft = 30.48 cm ≈ 30.5 cm. Not matching. Possibly misprint.

a) 6 b) 12 c) 14 d) 21
✅ Answer: c) 42 but not in options — recalc: Cost per pencil = 30/5=6, so 7 pencils = 42. Options wrong? They have 6,12,14,21. Possibly misprint.


Assertion-Reason

Q14:
A: Product of two natural numbers always greater than both.
R: Multiplication always increases value.
✅ Answer: (d) A false, R true
Explanation: If one number is 1, product equals the other. So A false. R: multiplication by number >1 increases, but not always.

Q15:
A: 5/10 = 1/2
R: Fraction unchanged if numerator/denominator divided by same nonzero number.
✅ Answer: (a) Both true, R explains A
Explanation: 5/10 ÷ 5/5 = 1/2.


Section B – Short Answers (2 marks)

Q16: Diagonal of square with side 5 cm.
✅ Answer: Diagonal = side√2 = 5√2 cm ≈ 7.07 cm.

Q17: Digital root of 8-digit number is 5. Digital root of number + 10?
✅ Answer: Adding 10 adds 1 to digital root sum → new digital root = 5+1 = 6 (since 10 ≡ 1 mod 9).

Q18: Compute 96² using identity.
✅ Answer: 96² = (100−4)² = 10000 − 800 + 16 = 9216.
OR Multiply 3874 × 101 = 3874 × (100+1) = 387400 + 3874 = 391,274.

Q19: If 3a7b8 divisible by 44, find possible a,b.
✅ Explanation: Divisible by 44 means divisible by 4 and 11.

  • Divisible by 4: last two digits b8 divisible by 4 → b=0,2,4,6,8.

  • Divisible by 11: (3+7+8) − (a+b) = multiple of 11 → 18 − (a+b) = 0 or 11 or… Try values.

Let’s solve: 18 − (a+b) = 0 ⇒ a+b=18 (max digit 9+9=18).
If 18 − (a+b) = 11 ⇒ a+b=7.
If 18 − (a+b) = −11 ⇒ a+b=29 (not possible).
So a+b=18 or 7. With b even from step 1.
Test b=0 → a=18 or 7 (a digit so ≤9) → a=7 works for a+b=7.
List pairs:
(a,b) = (7,0), (5,2), (3,4), (1,6), (8,8) for sum=7? Wait sum=7 cases:
(7,0),(5,2),(3,4),(1,6) yes.
Also sum=18: (9,9) but b=9 not even → no.
So possible: (7,0),(5,2),(3,4),(1,6).

Q20: TV bought ₹21,000, depreciates 5% yearly → value after 2 years?
✅ Answer: After 1 year: 21000×0.95 = ₹19,950.
After 2 years: 19950×0.95 = ₹18,952.5.
OR Profit/loss: SP of 3 pencils = CP of 5 pencils → Let CP per pencil = ₹1, CP of 5 = ₹5 = SP of 3 → SP per pencil = 5/3 ≈ 1.67 → Profit % = (0.67/1)×100 = 67%.


Section C – Short Answers (3 marks)

Q21: Scooter: 120 km in 3h → speed 40 km/h.
Train: 120 km in 2h → speed 60 km/h.
Ratio of speeds = 40:60 = 2:3.
OR Parking: cycles=115, scooters=75, bikes=45, total=235.
Ratio cycles:total = 115:235 = 23:47.

Q22: Isosceles right triangle hypotenuse = √72 → other sides?
✅ Answer: side√2 = √72 = 6√2 → side = 6. So sides 6,6.

Q23: Manju: ₹12,500 at 12% p.a. simple interest for 3 years.
Anju: same at 10% p.a. compound annually.
Who pays more interest and by how much?
✅ Answer:
Manju SI = 12500×0.12×3 = ₹4500.
Anju CI: A = 12500×(1.1)³ = 12500×1.331 = ₹16,637.5 → Interest = 16637.5−12500=4137.5.
Manju pays more by 4500−4137.5=₹362.5.

Q24(a): Simplify (am + bn)² − (am − bn)².
✅ Answer: = (a²m²+2abmn+b²n²) − (a²m²−2abmn+b²n²) = 4abmn.

(b): If a+b=8, a−b=4 → find a²+b².
✅ Answer: Add: 2a=12 → a=6, b=2.
a²+b² = 36+4 = 40.

Q25: Given Ξ”XDC in figure: AB=5 cm, AD=4 cm. Find area Ξ”XDC.
Need diagram. Likely rectangle ABCD, X on BC, triangle base DC=5, height=4 → Area = ½×5×4 = 10 cm².
OR Trapezium: parallel sides 6 in, 14 in, distance 10 in → Area = ½×10×(6+14) = 5×20 = 100 in².


Section D – Long Answers (4 marks)

Q26: Side of rhombus diagonals 24 cm and 70 cm.
✅ Answer: Side = √[(24/2)² + (70/2)²] = √(12²+35²) = √(144+1225) = √1369 = 37 cm.
OR Equilateral triangle side 6 m → height = 3√3 m, area = ½×6×3√3 = 9√3 m² ≈ 15.588 m².

Q27: Number remainder 3 when ÷7, another remainder 5 when ÷7. Remainder of sum ÷7?
✅ Answer: Sum remainder = (3+5) mod 7 = 8 mod 7 = 1.
OR Newspapers: English=216, Hindi=312−216=96.
Ratio English:Hindi = 216:96 = 9:4.
Ratio Hindi:Total = 96:312 = 8:26 = 4:13.

Q28: Population reduces 10% per decade. Current 1250 → after 4 decades?
✅ Answer: After each decade = 90% of previous. After 4 decades = 1250×(0.9)⁴ = 1250×0.6561 ≈ 820.


Section E – Case-Based (4 marks)

Q29: Hexagonal cake side 4 cm, 10 friends, equal pieces. Quantity each? Perimeter?
✅ Answer:
Area of hexagon = (3√3/2)×side² = (3√3/2)×16 = 24√3 cm² ≈ 41.57 cm².
Each friend gets ≈ 4.157 cm².
Perimeter = 6×4 = 24 cm.

Q30: Deepa earns ₹150,000/month.
Spends:

  • Food: 1/10 = ₹15,000.

  • Shopping: 1/4 = ₹37,500.
    Remaining = 150,000 − (15,000+37,500) = ₹97,500.
    Education: 1/5 of remaining = ₹19,500.
    Savings = 97,500 − 19,500 = ₹78,000.

(a) Food = ₹15,000.
(b) Education = ₹19,500.
(c) Savings = ₹78,000.

Assertion-Reason

Q14:
A: (a−b)² = (b−a)² for any integers a,b.
R: Square of any integer is positive.
✅ Answer: (b) Both true but R not correct explanation
Explanation: Equality holds because (a−b)² = (b−a)² due to squaring, not because squares are positive.

Q15:
A: Tiger population was m, increased by 5% in last decade.
R: Population now is 0.05m.
✅ Answer: (d) A true, R false
Explanation: Increase 5% → new population = m + 0.05m = 1.05m, not 0.05m.


Section B – Short Answers (2 marks)

Q16: Sum of 4 consecutive numbers = 34. Find them.
✅ Answer: Let numbers: n, n+1, n+2, n+3.
Sum = 4n+6 = 34 ⇒ 4n=28 ⇒ n=7 → 7,8,9,10.

Q17: Digital root of 9a + 36b + 13.
✅ Answer: Digital root = sum digits mod 9.
9a divisible by 9, 36b divisible by 9, 13 → digital root 1+3=4.

Q18: Express 100 as difference of two squares.
✅ Answer: 100 = 26² − 24²? Check: 26²=676, 24²=576, difference=100 ✔. Also 10²−0².

Section E – Case-Based (4 marks)

Q29: Giridhar: loan ₹12,500 at 12% p.a. simple interest for 3 years.
Raghu: same loan at 10% p.a. compound annually.

(a) Who pays more interest?
✅ Simple interest for Giridhar = P×r×t = 12500×0.12×3 = ₹4500.
Compound for Raghu: A = P(1+r)α΅— = 12500×(1.1)³ = 12500×1.331 = ₹16637.5, Interest = 16637.5−12500 = ₹4137.5.
Giridhar pays more (4500 > 4137.5).

(b) Difference in amount paid after 3 years?
✅ Giridhar amount = 12500+4500 = ₹17000. Raghu = ₹16637.5. Difference = 17000−16637.5 = ₹362.5.

(c) Who incurs loss?
✅ Neither loses; but Giridhar pays more interest, so borrower’s perspective: Giridhar has higher cost.


Q30: Toy: two trapeziums + rectangle in middle.

(a) Height of trapezium? Need dimensions from diagram. If given parallel sides and area, solve.

(b) Total area of toy?
