The price of a mobile is Rs 30,000. The value of the mobile depreciates by 12% at the end of the first year and at the end of next year, it depreciates by 15%. What will be the value of the mobile after 2 years?

Rs 22,440

The value after depreciation of r% = Original value x $\frac{100-r}{100}$

The price of mobile after successive depreciation of 12%, 15% = 30,000 x $\frac{88}{100} \; \frac{85}{100}$

                              = Rs 22,440
