Answer 2

Answer:

b. 8,9

Step-by-step explanation:

in all the cases we will take the bigger no. first and then the smaller no. while subtracting . we will not consider it as -1 or any other negative integer.. ok.

a) 12,6

here ,12 - 6 should be = 1

12-6 = 6 , which is not equal to 1

so its sure that it cannot be  the  answer .

next we have b. 8,9

9-8 = 1

1 = 1

lhs = rhs

then if its the correct ans , it must have its product as 72

9 x 8 = 72

72 = 72

hence b ) is the correct answer

next we have c. 7 , 8

8 - 7 = 1

1=1

lhs = rhs

atq if it is the answer , it s product must be 72

but , 8 x 7 = 56 ≠ 72

next we have 7,9

9-7 = 2 ≠ 1

hence, it is also not the correct answer

as only b satisfies all condition , the correct answer is b
