Question : If $x:y=3:4$, then $4x+5y:5x–2y=?$
Option 1: $7:32$
Option 2: $32:7$
Option 3: $4:3$
Option 4: $5:2$
Correct Answer: $32:7$
Solution : Given: $x:y=3:4$ --------------------------------(1) Or, $\frac{x}{y}=\frac{3}{4}$ Now, $(4x+5y):(5x–2y)$ Dividing by $y$ in the numerator and the denominator, we get, $[4(\frac{x}{y})+5]:[5(\frac{x}{y})–2]$ = $[4(\frac{3}{4})+5:5(\frac{3}{4})–2]$ (Putting the value of $\frac{x}{y}$ from equation 1) = $(3+5):(\frac{15}{4}–2)$ = $8:(\frac{15–8}{4})$ = $8:\frac{7}{4}$ = $32:7$ Hence, the correct answer is $32:7$.
