28

Step-by-step explanation:

6*7/2

5*4/2

7*8/2=28

Answer 2

Find out the correct answer for the unsolved equation based on a certain system: 6 × 7 = 21, 4 × 5= 10, 8 × 7 = ?

The correct answer is 8 × 7 =28

Given:

6 × 7 = 21, 4 × 5= 10

To Find:

8 × 7 =?

Solution:

Here a sort of sequence has been given in which there lies a relation.

So, if we clearly see 6 × 7 = 21, and 4 × 5= 10,

We will notice that if one of the numbers gets divided by 2 and then multiplied by another number, we will get the right value.

i.e,

6/2 = 3

Then, 3 × 7 = 21

Similarily,

4/2 = 2

Then, 2 × 5= 10

Thus if we progress in this way,

we will get,

8/2 = 4

Then,  4 × 7 = 28

Thus the correct answer is 28.
