Practice and master this topic with our carefully crafted questions.
If 2 & 6 % 7 = 33, 4 & 6 % 8 = 54, then what will be the value of 6 & 8 % 9 = ?
Here sign '&' does not convey any meaning and sign '%' signifies '+'
26 + 7 = 33, 46 + 8 = 54
Therefore, 68 + 9 = 77
If 16 - 2 = 2, 9 - 3 = 0, 81 - 1= 8, then what is 64 - 4 = ?
As, √ 16 - 2 = 4 - 2 = 2
√ 9 - 3 = 3 - 3 = 0
and √ 81 - 1 = 9 - 1 = 8
Similarly, √ 64 - 4 = 8 - 4 = 4
Change symbol and solve accordingly to find correct answer from the alternatives given below:
9 x 8 x 7 = 24, 4 x 7 x3 = 14, 2 x 1 x 9 = ?
As, 9 + 8 + 7 = 24
and 4 + 7 + 3 = 14
Similarly, 2 + 1 + 9 = 12
Note Here, sign of 'x' is converted into '+'.
If 879 = 8, 625 = 1 and 586 = 9, then 785 = ?
As, 879 = (7 + 9) - 8 = 8
625 = (2 + 5) - 6 = 1
and 586 = (8 + 6) - 5 = 9
Similarly, 785 = (8 + 5) - 7 = 6
