Solution


Q.

For an experimental expression y=32.3×112527.4, where all the digits are significant. Then to report the value of y we should write          [2025]
1 y = 1326.2  
2 y = 1326.19  
3 y = 1325.186  
4 y = 1330  

Ans.

(4)

y=32.3×112527.4=1326.186

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

∴  y = 1330
