Question

If 1+1=6,2+5=7, 3+4=9, 6+8=8then7+9=?

Answer 1

Answer:

8

Step-by-step explanation:

7+9=(2+5)+(3+4) -given

=2+5+3+4

=6+8 -rearrangement

=8 -given

Answer 2

Answer:

Answer is 18!!

Step-by-step explanation:

We have to think observe the pattern.

1+1=6

2+5=7

Now if we observe, 1 and 6 from the first term is making 7 i.e,

1+6=7, which is the answer for the second term.

Now similarly,

2+5=7

3+4=9

If we observe, 2 and 7 makes 9 i.e,

2+7=9, which is the third term.

So, we cam formulate this:-

If,

n+m =q

r+ s = t

Then, n+q=t

So,

6+8 = 12(i.e 3+9 from previous term)

7+9=18(i.e 6+12 from previous term)
