Solution No. 2:
🧠 Concept Recap:
Surface area of a cube = 6a^2
If side becomes a′=1.10a
Then surface area becomes:
6×(1.10a)^2=6×1.21a^2=7.26a^2
Original surface area= 6a^2
New surface area =7.26a^2
% Increase =(7.26a^2- 6a^2)/ 6a^2 *100
=21%

Solution No. 3:
total sum of 31 numbers= 31*40=1240
sum of first 16 numbers= 16*38=608
sum of last 16 numbers= 16*42=672
🧠 Key Insight:
The 16th observation is counted twice — once in the first 16 and once in the last 16.
So if we add: 608+672=1280
“1280” contains 16th observation twice.
But total sum of all 31 observations = 1240
Remove duplication= 1280-1240=40
This is the 16th number.

Solution No. 3:
🔹 Step 1: Prime Factorization of 3600
3600=36×100=(6^2)×(10^2)=(2×3)^2×(2×5)^2
3600=2^4×3^2×5^2
🔹 Step 2: Total Number of Divisors
formula: If n=p^a×q^b×r^c
Then, Number of divisors=(a+1)(b+1)(c+1)
Total divisors=5×3×3=45
45 includes:
1 (which is not a proper divisor)
3600 itself (also not a proper divisor)
🔹 Step 3: Subtract 1 and the Number Itself
Proper divisors=45−2=43
🔹 Step 1: Prime Factorization of 3600
3600=36×100=(6^2)×(10^2)=(2×3)^2×(2×5)^2

🔹 Step 2: Total Number of Divisors
formula: If n=p^a×q^b×r^c
Then, Number of divisors=(a+1)(b+1)(c+1)
Total divisors=5×3×3=45
