Question 17

If (5/9 of x) - (2/5 of 9/4) equals -4/5 then find x.

Solution

According to question, => $$(\frac{5}{9} \times x)-(\frac{2}{5} \times \frac{9}{4})=\frac{-4}{5}$$

=> $$\frac{5x}{9} - \frac{9}{10} = \frac{-8}{10}$$

=> $$\frac{5x}{9} = \frac{9}{10}-\frac{8}{10} = \frac{1}{10}$$

=> $$x = \frac{9}{50} = 0.18$$

=> Ans - (A)
