Question : Directions: If 16 ÷ 4 = 74, 21 ÷ 7 = 33, 81 ÷ 9 = 99 then 55 ÷ 5 =?
Option 1: 110
Option 2: 1001
Option 3: 11
Option 4: 1011
Correct Answer: 1011
Solution :
Given:
16 ÷ 4 = 74, 21 ÷ 7 = 33, 81 ÷ 9 = 99 then 55 ÷ 5 =?
Here, the pattern follows the formula ⇒ (ab ÷ c) = (a + b), (ab ÷ c) (Both the answers written side by side)
Like, 16 ÷ 4 = (1 + 6), (16 ÷ 4) = 74
21 ÷ 7 = (2 + 1), (21 ÷ 7) = 33
81 ÷ 9 = (8 + 1), (81 ÷ 9) = 99
Similarly, 55 ÷ 5 = (5 + 5), (55 ÷ 5) = 1011
So, 1011 is the required number. Hence, the fourth option is correct.
