... absolute, relative and percentageerrors.Sol. Given that True value ()1 3 x=, and its Approximate value (x′) = 0 .33 3Therefore, Absolute Error, 10 .33 3 0 .33 333 3 0 .33 3 0.00 033 3 3 a Exx′=− ... of these three is the best approximation?Sol. The number, which has least absolute error, gives the best approximation.True value x =10 .33 333 3 =When approximate value x′ is 0 .30 the Absolute ... 0.0015The error affects the third decimal place, therefore, (0.491) 3 = 0.11 83 is correct to seconddecimal places.Example 4. If 0 .33 3 is the approximate value of 1 3 , then find its absolute, relative...
