Question

If (4x+5):(3x+11)=13:17, then (5x+4): (4x-1)= ?

A.

3:2

B.

2:1

C.

4:3

D.

5:2

Correct option is B

Given Data:(4x+5):(3x+11)=13:17We need to find (5x+4):(4x1).Step 1: Convert Ratio into an Equation4x+53x+11=1317Step 2: Solve for xCross multiply:(4x+5)×17=(3x+11)×1368x+85=39x+143Rearrange:68x39x=1438529x=58x=2Step 3: Compute (5x+4) and (4x1)Substituting x=2:5x+4=5(2)+4=10+4=144x1=4(2)1=81=7Step 4: Compute the Ratio(5x+4):(4x1)=14:7=2:1\textbf{Given Data:}\\(4x + 5) : (3x + 11) = 13 : 17\\\text{We need to find } (5x + 4) : (4x - 1).\\\textbf{Step 1: Convert Ratio into an Equation}\\\frac{4x + 5}{3x + 11} = \frac{13}{17}\\\textbf{Step 2: Solve for } x\\\text{Cross multiply:}\\(4x + 5) \times 17 = (3x + 11) \times 13\\68x + 85 = 39x + 143\\\text{Rearrange:}\\68x - 39x = 143 - 85\\29x = 58\\x = 2\\\textbf{Step 3: Compute } (5x + 4) \text{ and } (4x - 1)\\\text{Substituting } x = 2:\\5x + 4 = 5(2) + 4 = 10 + 4 = 14\\4x - 1 = 4(2) - 1 = 8 - 1 = 7\\\textbf{Step 4: Compute the Ratio}\\(5x + 4) : (4x - 1) = 14 : 7\\\quad = 2 : 1​​
