Divide 45 into four parts such that when 2 is added to the first part, 2 is subtracted from the second part, 2 is multiplied by the third part and the fourth part is divided by two, all result in the same number.
(a) 8, 12, 5, 20
(b)6,10,15,11
(c)2,8,14,9
(d)none of these

• (a) 8, 12, 5, 20
  
  If x is common result, then numbers are 2x, x/2, x+2, x-2
  and
  2x+ x/2+ x+2+x-2 = 45
  4x+x/2 =45
  9x =90
  x=10
  hence numbers are
  8,12,5,20 .... option (a)

• (a) 8, 12, 5, 20
  Reason: 8+12+5+20 = 45
  8+2 = 10
  12-2 = 10
  5*2 = 10
  20/2 = 10
  All numbers are same which is 10.

• The answer is option (a) 8, 12, 5, 20
  According to the ques, 8+2=10
  12-2=10
  5*2=10
  20/2=10 which is the same number

  Explanation:
  a + b + c + d =45;
  a+2 = b-2 = 2c = d/2;
  a=b-4; c = (b-2)/2;
  d =2(b-2);
  b-4 + b + (b-2)/2 + 2(b-2) = 45;.
