Q2. The geometric mean of 4 and 16 is:
A 12
B 10
C 8 Correct
D 6
Explanation
Geometric Mean of two numbers a and b = √(a × b) = √(4 × 16) = √64 = 8. Note: GM is always ≤ AM. Here AM = (4+16)/2 = 10 > 8 = GM.
Q3. The compound amount on ₹16,000 at 20% per annum for 1 year, compounded half-yearly, is:
A ₹19,500
B ₹19,200
C ₹19,000
D ₹19,360 Correct
Explanation
Half-yearly rate = 20/2 = 10%. Number of periods = 2 (for 1 year). A = P(1 + R/100)ⁿ = 16000 × (1 + 10/100)² = 16000 × (1.1)² = 16000 × 1.21 = ₹19,360.
Q4. A line graph shows temperature (°C) over 5 days: Mon=32, Tue=35, Wed=30, Thu=28, Fri=35. The average temperature is:
A 31°C
B 30°C
C 33°C
D 32°C Correct
Explanation
Average = (32+35+30+28+35)/5 = 160/5 = 32°C.
Q5. A sum of money becomes double in 5 years at simple interest. The rate of interest per annum is:
A 15%
B 20% Correct
C 25%
D 10%
Explanation
If the sum doubles, then SI = P (the interest equals the principal). SI = P×R×T/100, so P = P×R×5/100. Therefore R×5 = 100, and R = 20%. General formula: For sum to become n times in T years at SI, Rate = (n-1)×100/T.
