Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. ÷, −, ÷, +, =
121 * 11 * 99 * 11 * 77 * 79
Putting signs of option 1( ÷, −, ÷, +, =) in equation
121 ÷ 11 - 99 ÷ 11 + 77 = 79
11 - 9 + 77 = 79
2 + 77 = 79
79 = 79
No need to check further.
Hence, ÷, −, ÷, +, = is the correct answer.
