Hello,
Consider the given 9 - 5 as (9-5) / 2 = 2.
Similarly, 25 - 15 is (25 - 15) / 2 = 10/2 = 5.
Therefore, 12 - 6 is (12 - 6) / 2 = 6 / 2 =3.
Hindi: " jo numbers left hand side me diye gaye hai, uska direct subtraction karne ke baad, jo result milta hai, usko 2 se divide karna hai.. answer paane keliye"
Hope this helps.
Thanks.
