Question

Answer 1

Answer:

(1) 431

Step-by-step explanation:

It's Given that 54 + 43 = 79 and 60 + 51 = 111 then what's the value of 62 + 72.

If we do simple addition then it's like

→ 54 + 43 = 97

But the given value is 79 instead of 97. Means after addition digits are interchanged.

Similarly,

60 + 51 = 111

It will be remian same, as numbers are same.

Now,

62 + 72 = 134

Now, once again we have to change the first and last digit to get the desired answer.

If we change 4 with 1 and 1 with 4. We get, 431.

Hence, 62 + 72 is 431.

Option (1) 431.
