The price of a mobile phone was 18,000 last year. It has increased by 15$$\frac 34$$​% this year. What is the current price?

Correct option is D

Given:
Last year price = 18,000
Increase = 15$$\frac 34$$​% = 15.75%
Formula Used:
​$$\text{New Price} = \text{Old Price} \times \left(1 + \frac{\text{Increase}\%}{100}\right)$$​​
Solution:
15.75% = $$\frac{15.75} { 100}$$​ = 0.1575
Increase = 18,000 × 0.1575 = 2835
Current price = 18,000 + 2835 = 20,835
Alternate Solution:
​$$15 \frac{3}{4}\% = \frac{63}{4}\%\\\ \\\text{New Price} = 18000 \times \left(1 + \frac{63}{400}\right)\\\ \\= 18000 \times \frac{463}{400}\\\ \\= 20835$$​​
