If the sum of 4 times a number A and 3 times a number B is equal to the sum of number B and seven times the number A, then what is the value of A:B?
a, 2:3 b,3:2 c, 4:3 d, 3:4

• a) 2 : 3
  
  Given:
  4A + 3B = B + 7A
  => 2B = 3A
  => A/B = 2/3
  => A : B = 2 : 3

• ans is a 2:3
• 9 years agoHelpfull: Yes(1) No(1)
• 4 A+ 3 B=1 B+ 7 A
  3 B-1 B=7 A-4 A
  2 B=3 A
  B/A=3/2
  A:B=2:3

• 4a + 3b = b + 7a
  3a = 2b
  a/b = 2/3
  
  Ans . a) 2:3

• 4a+3b=b+7a
  a/b=2:3
• 4 years agoHelpfull: Yes(0) No(0)
• 4A+3B=B+7A
  3B-B=7A-4A
  2B=3A
  A:B=2:3

• 2:3
  given 4A+3B=B+7A THEN
  7A-4A=3B-B
  3A=2B
  A:B=2:3
