Question

if 2x-1: 3x+1 is duplicate ratio of 3:4, then the value of x and the sub duplicate ratio of 4x+5 : 7x+1 after putting the value of x

Answer 1

Answer:

Given: (x−9):(3x+6) is the duplicate ratio of 4:9

⇒3x+6x−9=(94)2

⇒3x+6x−9=8116

⇒81x−729=48x+96

⇒81x−48x=96+729

⇒33x=825

⇒x=33825=25

Answer 2

Step-by-step explanation:

(2x + 1): (3x + 13) is the sub-duplicate ratio of 9: 25

Then the sub-duplicate ratio of 9: 25 = 3: 5

(2x + 1)/ (3x + 13) = 3/5

10x + 5 = 9x + 39

x = 34
