The given bar graph represents both, theoretical and practical readings obtained in 5 rounds of readings while conducting a scientific experiment. What is the ratio of the difference obtained in readings 2 and 5 when calculated theoretically to the difference obtained in readings 1 and 3 when readings were taken practically?

The given bar graph represents both, theoretical and practical readings obtained in 5 rounds of readings while conducting a scientific experiment. What is the ratio of the difference obtained in readings 2 and 5 when calculated theoretically to the difference obtained in readings 1 and 3 when readings were taken practically? Correct Answer 5 : 2

Given:

  Reading 1 Reading 2 Reading 3 Reading 4 Reading 5
Theoretical 125 127 125 130.12 132
Practical 124.5 127.2 126.5 129.86 132.4

 

Calculations:

Difference obtained in readings 2 and 5 when calculated theoretically = 132 - 127 = 5

Difference obtained in readings 1 and 3 when readings taken practically = 126.5 - 124.5 = 2

Ratio = 5 : 2

∴ The required ratio is 5 : 2.
