Question

If 532 + 781 = 15 and 862 + 910 = 19 then what is value of 796 + 355

Answer 1

Answer:

21

Step-by-step explanation:

As we add first and last digit of each term...5+2 + 7+1 = 15

8+2 + 9+0 = 19

7+6 + 3+5 = 21

Answer 2

Answer:

The value of $796 + 355=21$

Step-by-step explanation:

We are given that $532 + 781 = 15$

and

$862 + 910 = 19$

We need to determine the value of $796 + 355$

It is clear that it is not normal addition, as the result is very small.

So a different logic is followed here.

We need to determine the logic which is same in both the given equalities.

From first equation,

$532 + 781 = 15$

add first and last digit of both numbers,

$5+2+7+1=15$

Similarly in $862 + 910 = 19$

$8+2+9+0=19$

Applying same logic in third one also

$796 + 355$

$7+6+3+5=21$
