Complete CMAT Arithmetic Formulas List
Below is a complete list of important CMAT Arithmetic formulas for quick revision.
Percentages
Percentage Change
Percentage Change = [(New Value − Old Value) / Old Value] × 100
Percentage Increase or Decrease Multiplier
Final Value = Original Value × (1 ± k/100)
where k is the percentage increase or decrease.
Original Value from Final Value
Original Value = Final Value / (1 ± k/100)
Successive Percentage Change
Net Percentage Change = a + b + (ab/100)
(Use positive sign for increase and negative sign for decrease.)
Profit and Loss
Profit and Loss
Profit = SP − CP
Loss = CP − SP
Profit Percentage
Profit% = (Profit / CP) × 100
Loss Percentage
Loss% = (Loss / CP) × 100
Selling Price
SP = CP × (1 + Profit%/100)
Cost Price
CP = SP / (1 + Profit%/100)
Discount Percentage
Discount% = [(MP − SP) / MP] × 100
Successive Discounts
Net Discount% = a + b − (ab/100)
Required Marked Price
MP = [CP × (1 + Desired Profit%/100)] / (1 − Discount%/100)
Simple and Compound Interest
Simple Interest
SI = (P × R × T) / 100
Amount in Simple Interest
Amount = P + SI
Compound Interest
Amount = P(1 + R/100)^T
Compound Interest
CI = Amount − Principal
Compound Interest (Compounded m Times Per Year)
Amount = P(1 + R/100m)^(mT)
Difference Between CI and SI for 2 Years
CI − SI = P(R/100)^2
Rule of 72
Time to Double ≈ 72 / Rate of Interest
Time, Speed and Distance
Basic Formula
Speed = Distance / Time
Distance = Speed × Time
Time = Distance / Speed
Conversion
1 km/h = 5/18 m/s
1 m/s = 18/5 km/h
Average Speed for Equal Distances
Average Speed = (2ab)/(a + b)
Relative Speed
Opposite Direction = a + b
Same Direction = |a − b|
Train Crossing Pole
Time = Length of Train / Speed
Train Crossing Platform
Time = (Length of Train + Length of Platform) / Speed
Boats and Streams
Downstream Speed = b + s
Upstream Speed = b − s
where b = speed of boat in still water and s = speed of stream.
Time and Work
Work Rate
Work Rate = 1 / Time Taken
Combined Work
1/T = 1/a + 1/b
where a and b are individual times and T is combined time.
Efficiency and Time Relationship
Efficiency ∝ 1/Time
Higher efficiency means less time required.
Pipes and Cisterns
Net Work Rate = Filling Rate − Emptying Rate
Ratio and Proportion
Proportion
a : b = c : d ⟺ ad = bc
Fourth Proportional
d = (b × c) / a
Compound Ratio
(a : b) × (c : d) = ac : bd
Division of Quantity in Ratio
Share of A = [a / (a + b)] × Total
Share of B = [b / (a + b)] × Total
Averages
Simple Average
Average = Sum of Observations / Number of Observations
Weighted Average
Weighted Average = Σ(wᵢxᵢ) / Σwᵢ
New Sum After Addition or Removal
New Sum = Old Average × n ± Value Added/Removed
Running Average Update
New Average = Old Average + (New Value − Old Average)/New Count
