Bank Exam Quant – Arithmetic (Profit & Loss, SI-CI, Time & Work)
Arithmetic is the most important section in quantitative aptitude. Questions are concept-based and require proper understanding and practice.
1. Profit & Loss
Formulas:
- Profit = SP - CP
- Loss = CP - SP
- Profit % = (Profit / CP) × 100
Example:
CP = 100, SP = 120
Profit = 20 → Profit % = 20%
2. Simple & Compound Interest
Formulas:
- SI = (P × R × T) / 100
- CI = P(1 + R/100)T
Example:
P = 1000, R = 10%, T = 1
SI = 100
3. Time & Work
Work = Time × Efficiency
Example:
A completes work in 10 days
→ 1 day work = 1/10
Practice Questions
Q1 (Profit):
CP = 200, SP = 250
→ Profit % ?
Q2 (SI):
P = 1000, R = 5%, T = 2
→ SI ?
Q3 (Time & Work):
A completes work in 5 days
→ 1 day work ?
Answers
Q1: 25%
Q2: 100
Q3: 1/5
