Q1. Simple Interest

Find SI for P = 2000, R = 5%, T = 3 years

Solution:
SI = (P × R × T) / 100
= (2000 × 5 × 3) / 100
= 300

---

Q2. Compound Interest

Find CI for P = 1000, R = 10%, T = 2 years

Solution:
Amount = 1000 × (1.1)² = 1210
CI = 1210 - 1000 = 210

Q3. Ratio & Proportion

If a : b = 3 : 4 and b : c = 2 : 5, find a : b : c

Solution:
Make b equal → LCM of 4 and 2 = 4
a : b = 3 : 4
b : c = 4 : 10
Answer = 3 : 4 : 10

Q4. Data Interpretation (Approximation)

498 × 102 ≈ ?

Solution:
498 ≈ 500
102 ≈ 100
= 500 × 100 = 50000

Q5. Percentage Change

A value increases from 200 to 260. Find percentage increase.

Solution:
Increase = 60
% Increase = (60/200) × 100 = 30%
