Directions for Qns : If the given interchanges are made in signs and numbers, which one of the four equations would be correct
 1. If 2 & 6 % 7 = 33, 4 & 6 % 8 = 54, then what will be the value of 6 % 8 & 9 77 95 99 None of these opt 5 ANSWER : 95 Explanation : . Here sign & does not convey any meaning and sign % signifies +. 26 + 7 = 33, 46 + 8 = 54. Therefore, 6+ 89 = 95.
 2. Given interchanges signs `+’ and `-‘ ; numbers `5’ and `8’. 82 – 35 + 55 = 2 82 – 35 + 55 = 102 85 – 38 + 85 = 132 52 – 35 + 55 = 72 opt 5 ANSWER : 82 – 35 + 55 = 2 Explanation : . 1. 52 + 38 -88 = 2
 3. Given interchanges signs `-‘ and `÷’ ; numbers `2’ and `6’. 32 – 12 ÷ 6 = 30 36 ÷ 12 – 2 = 1 32 – 16 ÷ 6 = 1 36 – 12 ÷ 2 = 30 opt 5 ANSWER : 31 – 16 ÷ 6 = 1 Explanation : . 1. 36 ÷ 16 – 2 30
 4. Given interchanges signs `+’ and `x’ ; numbers `3’ and `7’. 23 + 17 x 73 = 1241 37 + 73 x 12 = 112 23 x 17 + 37 = 428 23 + 17 x 73 = 388 opt 5 ANSWER : 23 + 17 x 73 = 388 Explanation : . 1. 27 x 13 + 37 1241
 5. Given interchanges signs `+’ and `x’ ; numbers `1’ and `3’. 31 + 34 x 31 = 1085 31 + 34 x 31 = 395 13 + 34 x 13 = 195 31 + 14 x 13 = 213 opt 5 ANSWER : 31 + 34x 31 = 395 Explanation : . 1. 13 x 14 + 13 3085
