. If a and b are positive integers and (a-b)/3.5 = 4/7, then

(A) b < a (B) b . a (C) b = a (D) b .= a

• option a is correct ....(a-b)/3.5 = 4/7
  means a-b = 2 .
  so option A clearly says that a is greater than b....which is correct

• (a-b)=(3.5*4)/7=2
  a=2+b so,b

• the question is (a-b)/3.5 = 4/7
  sol:
  (a-b)=(4/7)3.5
  convert 3.5 without decimal by mul and divide by 10
  (a-b)=(4/7)(35/10)
  a-b=2
  the answer is positive so obivously the number a should be greater
  option A is correct

• (a-b)/3.5=4/7
  => a-b=2
  =>a=b+2
  Hence, a>b
  option(A)

• A. (a-b)=(4*3.5)/7=2 thats -b

• * Multiplying both sides by 3.5 , we get */
