Correct Answer - Option 1 : 8
Concept:
nth term of A.P are a, a + d , a + 2d, . . . . ,a + (n-1)d .
Tn = a + ( n - 1 ) d
Where a = first term and d = common difference
Calculation:
Two-digit numbers are divisible by 12 are 12, 24 . . . . 96
Last number is 96
As we know that , Tn = a + ( n - 1 ) d
⇒ 96 = 12 + ( n - 1 )12
⇒ 84 = ( n- 1 )12
⇒ 7 = n - 1
⇒ n = 7 + 1 = 8.
The correct option is 1
