A shorts costs m120. The price increase by 10%. Find the new price.

The price increases by $10\%$.

$$\text{Increase amount} = 10\% \text{ of m}120$$ $$\text{Increase amount} = \frac{10}{100} \times 120$$ $$\text{Increase amount} = 0.10 \times 120$$ $$\text{Increase amount} = \text{m}12$$

The new price is the original price plus the increase amount.

$$\text{New price} = \text{Original price} + \text{Increase amount}$$ $$\text{New price} = \text{m}120 + \text{m}12$$ $$\text{New price} = \text{m}132$$

The new price is $\text{m}132$.
