How do you do a profit and loss question?

Now let us learn some tricks or formulas to solve maths problems based on gain and loss.

  1. Profit, P = SP – CP; SP>CP.
  2. Loss, L = CP – SP; CP>SP.
  3. P% = (P/CP) x 100.
  4. L% = (L/CP) x 100.
  5. SP = {(100 + P%)/100} x CP.
  6. SP = {(100 – L%)/100} x CP.
  7. CP = {100/(100 + P%)} x SP.
  8. CP = {100/(100 – L%)} x SP.

Why is SPC needed?

How can objects be moved?

Force can make things move, change shape or change their speed. Some forces are direct and happen when two things touch (like a foot kicking a ball) or over a distance (such as a magnet or gravity). Friction is the force between two objects in contact with each other that will resist an attempt to move them.
