If 1 – 3 + 4 = 100, 4 – 6 + 9 = 999 and 2 – 6 + 7 = 879 Then 3 -3+6 = ?

Question

If
1-3+4=100,
4-6+9=999,
2-6+7=879
then
3-3+6=???

Answer 1

Answer is 220
i) 1 – 3 + 4 = 100,
If we solve it we get;
1 – 3 + 4 = -2+4 = 2
So 2 = 100.

ii) 4 – 6 + 9 = 999
we get 7 = 999

iii) 2 – 6 + 7 = 879
We get 3 = 879

Now we need to solve the last equation for which we need the answer;

So 3 -3 +6 = 6

we need to find the value of 6 which from above (i) + (ii) – (iii);

So 100 + 999 – 879 = 220
So 6 = 220

Answer 2

i) 1-3+4 = 100
ii) 4-6+9 = 999
iii) 2-6+7 = 879
Let us solve (ii)-(iii)+(i)
== (4-6+9) - (2-6+7) + (1-3+4) = 999 - 879 + 100 (= 22
== (4-2+1) - (6-6+3) + (9-7+4) = 220
== 3 - 3 + 6 = 220
