‘a’ is greater than ‘b’ by 2 and ‘b’ is greater than ‘c’ by 10.
If a + b + c = 130, then (b +c) – a = ?
1) 38
2) 42
3) 44
4) 34
5) None of these

• ans: 34
  a=b+2 ; b=c+10 hence a=c+12; a+b+c=130
  solving this a=48 , b=46 , c=36
  (b+c)=46+36=82-a=82-48=34

• The question is not clear. wat do you mean by ‘a’,‘b’,‘c’ and –? we can see only greek and latin here

• Here,
  a=b+2
  b=c+10
  now put the above value in a+b+c=130 so,
  a+b+c=130
  b+2+b+b-10=130
  3b-8=130
  3b=138
  so, b=46
  a=48
  c=36
  now, (b+c)-a=(46+36)-48=34
  so, Ans.:34

• ans-44
  a=b+2
  c=c+10
  a+b+c=130
  2+b+b+c=130
  2b+c=128
  2(c+10)+c=128
  c=36
  b=c+10
  b=46
  similarly,a=38
  putting values,
  b+c-a=44

• a+b+c=130
  since, a>b by 2......then equation is : a-b=2......therefore,a=b+2
  since, b>c by 10.........then equation is : b-c=10..........therefore, c=b-10
  substitute the value of a and c in a+b+c=130
  you will get b=46,then
  substitute b in a=b+2,c=b-10
  you will get values of: a=48,b=46,36
  substitute them in (b+c)-a=you will get 34

• a+b+c=130
  a=b+2
  b=c+10
  c=b-10
  b+2+b+b-10=130
  b=46
  a=48
  c=36
  therefore (b+c)-1=34
