For an experimental expression y = 32.3 x 1125 / 27.4 where all the digits are significant.

Question

For an experimental expression \(\mathrm{y}=\frac{32.3 \times 1125}{27.4}\), where all the digits are significant. Then to report the value of y we should write :

(1) \(y=1326.2\)

(2) \(y=1326.19\)

(3) \(y=1326.186\)

(4) \(y=1330\)

Answer 1

Correct option is : (4) y = 1330

\(\mathrm{y}=\frac{32.3 \times 1125}{27.4}=1326.186\) 

Last significant digits are 3 in operands so results should rounded off to 3 digits.

\(\therefore \) y = 1330
