Question

13/19=4

17/9=10 then

128/32=?

Answer 1

The missing number will be 20 to complete the given series.

Step-by-step explanation:

Note: There is an error in the question. 71 is mistyped as 17. Please see the solution based on the series  

13      19    4

71      9     10

128    32    ?

We write the above as follows:

 13 + 19 = 32 / 4   = 8

 71 +  9  = 80 / 10 = 8

128 + 32 = 160 / x = 8

So we get 160/x = 8

Therefore x = 160 / 8 = 20

So the missing number will be 20 to complete the given series.

13      19    4

71      9     10

128    32   20
