Question

If 1 +2 is 21 and 2 + 3 is 36 what is 4 + 5

Answer 1

4+5 would be 9 because you add 4 and 5

Answer 2

`4+5=65`

Explanation:

First term:

Step 1: We need to add the numbers.

`\Rightarrow 1+2=3`

Step 2: We need to multiply the obtained number with ‘7’.

`\Rightarrow 1+2=3 * 7=21`

Step 3: We need to add the obtained number with ‘0’.

`\therefore 1+2=3 * 7=21+0=21`

Second term:

Step 1: We need to add the numbers.

`\Rightarrow 2+3=5`

Step 2: We need to multiply the obtained number with ‘7’.

`\Rightarrow 2+3=5 * 7=35`

Step 3: We need to add the obtained number with ‘1’.

`\therefore 2+3=5 * 7=35+1=36`

Thus, third term will:

Step 1: We need to add the numbers.

`\Rightarrow 4+5=9`

Step 2: We need to multiply the obtained number with ‘7’.

`\Rightarrow 4+5=9 * 7=63`

Step 3: We need to add the obtained number with ‘2’.

`\therefore 4+5=9 * 7=63+2=65`

Since, the options are not given, we can take the liberty to apply any method in this problem.
