Question

9=90
8=72
7=56
6=72
3=?

Answer 1

Answer:

The value corresponds to 3 in this pattern  =12

Step-by-step explanation:

Given

9 = 90

8 = 72

7 = 56

6 = 72

To find

The value of 3

Solution:

9 = 90 = 9×10 = 9(9+1)

8 = 72 = 8 ×9 = 8(8+1)

7 = 56 =  7 ×8 = 7(7+1)

6 = 42 =  6 ×7 = 6(6+1)

------------------------------

Following this pattern we can conclude that

n = n(n+1)  -----------------------------(1)

To find the value 3, substitute the value of 'n' as 3

3 = 3(3+1) = 3×4 = 12

The value corresponds to 3 in this pattern  =12

Answer 2

Correct Question :

If 9 = 90 , 8 = 72 , 7 = 56 , 6 = 42 then find 3 = ?

Answer:

If 9 = 90 , 8 = 72 , 7 = 56 , 6 = 42 then 3 = 18

Step-by-step explanation:

Given :

we are given some relations

9 = 90 , 8 = 72 , 7 = 56 , 6 = 42

To Find :

The value of 3 = ?

Solution :

Since given relations are

9 = 90 , 8 = 72 , 7 = 56 , 6 = 42

observing the relations we get that

9 x 10 = 90

8 x 9 = 72

7 x 8 = 56

6 x 7 = 42

we can clearly observe that the next relation will can be get by multiplying 3 to 6

then

3 x 6 = 18

Hence we have calculated the value of 3 = 18
