Answer» Correct Answer - Option 3 : 111.1 Given : (X/Y) × 100 = 90 To find : (Y/X) × 100 Calculation : \(\frac{X}{Y} × 100 = 90\) \( \Rightarrow X = \frac{9}{{10}}\;Y\) -----(1) Now, \(\frac{Y}{X} × 100\) Putting the value of X from (1) \( = \;\frac{Y}{{\frac{{9Y}}{{10}}}} × \;100\) = (10/9) × 100 = 1000/9 = 111.11 ∴ Y is 111.11% of X |
