- Unitary Method – Unitary method is the method in which value of the required number of units are found after calculating the value of one unit.
| For example, if we are given that 10 pens cost Rs 100 and we need to find the cost of 5 pens, then we will first find the cost of one pen i.e. 100/10 = 10 Rs. When the value of one unit is known, we can multiply it with the required number of units i.e. 10 × 5 = 50 Rs. |
