Question 12 Which of the following statement(s) mean the same as — “The demand for cameras has fallen by 85% in the last decade”? (i) The demand now is 85% of the demand a decade ago. (ii) The demand a decade ago was 85% of the demand now. (iii) The demand now is 15% of the demand a decade ago. (iv) The demand a decade ago was 15% of the demand now. (v) The demand a decade ago was 185% of the demand now. (vi) The demand now is 185% of the demand a decade ago.Given Demand has fallen by 85% Now, "Fallen by" means we subtract. If you lose 85% of something, you are left with 100%−85%=𝟏𝟓%. So, the demand now is 𝟏𝟓% of what it used to be. Thus, the correct statement is (iii) - The demand now is 𝟏𝟓% of the demand a decade ago.
