Answer : 5 x 4 (Option C)
Step-by-step explanation : 5 + 5 + 5 + 5 = 20
By trial & error method, we get
5 x 2 = 10 ≠ 20
5 x 4 = 20
5 x 5 = 25 ≠ 20
5 x 10 = 50 ≠ 20
Hence 5 x 4 is the right answer
You can either follow the trial & error method or the following method !!
5 + 5 + 5 + 5 has ' 4 ' fives
Hence, 5 + 5 + 5 + 5 = 5 (since it is the no) x 4 (since it is the no of times 5 is repeating)
Hence 5 x 4 is the right answer
