Ans : 43

We have to find the HCF( Highest common factor of first and third colomn)
ie HCF OF 30 AND 25 IS 5
HCF OF 28 AND 36 IS 4
HCF OF 32 AND 24 IS 8

NOW dividing first row number with its hcf ie 30 / 5 is 6 and third coloum ie 25 / 5 is 5 therefore the number in middle row is 65

Similarly dividing second row number with its hcf ie 28 /4 is 7 and 36 / 4 is 9 thus the number of middle colomn is 79

therfore applying same logic 32 is divided by its hcf 8 we get 4 and 24 /8 is 3 so the answer to the problem is 43
