Question (v) – Page 131 PQ × 8 = RS.Here, we multiply a two-digit number by 8 to get a two digit number So, let’s check some numbers starting from 10 For 10: 10 × 8 = 80 (P and S are the same in this case, not possible) For 11: 11 × 8 = 88 (R and S are the same in this case, not possible) For 12: 12 × 8 = 96 (This can be possible) For 13: 13 × 8 = 104 (This is a 3-digit number, not possible) So, the only possible case is 12 × 8 = 96 Thus, our answer is P = 1, Q = 2, R = 9, S = 6
