If 3$7 = 26, 5$8 = 45 and 7$9 = 68, then find the value of 6$12 = ?
1). 72
2). 75
3). 77
4). 89
The logic followed here is:
3$7 = 26 " (3 × 7) + 5 = 26
5$8 = 45 " (5 × 8) + 5 = 45
7$9 = 68 " (7 × 9) + 5 = 68
6$12 = (6 × 12) + 5 = 77
Hence, ‘77’ is the correct alternative.2. If 9 # 3 = 6; 15 # 3 = 9; 60 # 4 = 32; then what is the value of 27 # 3 = ?
