गणना:

माना गुणा की  वाली संख्या x है

अतः, सही गुणन = (5/4)x

और गलत गुणन = (4/5)x

∴ गणना में प्रतिशत त्रुटि = 

\(\left[ {\frac{{\left( {\frac{5}{4}} \right)x - \left( {\frac{4}{5}} \right)x}}{{\left( {\frac{5}{4}} \right)x}}} \right] \times 100 = 36\% \)

माना संख्या 20 है (चूंकि 4 और 5 का एलसीएम 20 है)

सही गुणन = 20 × (5/4) = 25

गलत गुणन = 20 × (4/5) = 16

त्रुटि = 25 - 16 = 9

प्रतिशत त्रुटि = (9/25) × 100 = 36%

∴ प्रतिशत त्रुटि 36% है
