1. Important Maths formulas for the
upcoming
All India Law Entrance Test

2. ● Speed = Distance / Time
● Meeting points’ distance from starting point = (S1 * S2 * Difference in
time) / (Difference in speed)
● Average = (Total of data) / (No. of data)
● If a person travels a distance at a speed of x km/hr and the same space at
a y km/hr, then the average rate during the whole journey is given by –
2xy / (x+y) km/hr.
● If the current age is x, then n times the age is nx

3. ● Profit = Selling Price (SP) – Cost Price (CP)
● Loss = Cost Price (CP) – Selling Price (SP)
● Gain or Loss % = (Loss or Gain / CP) * 100 %

4. ● If M1 persons can do W1 work in D1 days and M2
persons can do W2 work in D2 days, then the formula
will be – M1 * D1 * W1 = M2 * D2 * W2
● If a pipe can fill a tank in x hours, the part filled in 1
hour = 1/x.
