Question
The market value of a laptop falls by 8% in the first year
and 15% in the second year. If the value after two years is Rs. 19,320, find the original price.Solution
ATQ,
Net percentage change = –8% –15% + {[(–8%) × (–15%)]/100}%= –23% + 1.2% = –21.8%
Let the present value be Rs. ‘x’
Then, 78.2% of x = 19320
Or, 0.782 × x = 19320
Or, x = 19320 / 0.782 = 24700
So, the original price of the laptop = Rs. 24,700
