Answer» thanks sir (i) 2724Here, 2 + 7 + * + 4 = 13 + * should be a multiple of 3.To be divisible by 3, the least value of * should be 2, i.e., 13 + 2 = 15, which is a multiple of 3.∴ * = 2 (ii) 53046Here,5 + 3 + * + 4 + 6 = 18 + * should be a multiple of 3.As 18 is divisible by 3, the least value of * should be 0, i.e., 18 + 0 = 18.∴ * = 0 (iii) 81711Here, 8+ * + 7 + 1 + 1 = 17 + * should be a multiple of 3.To be divisible by 3, the least value of * should be 1, i.e., 17 + 1 = 18 , which is a multiple of 3.∴ * = 1 (iv) 62235Here, 6 + 2 + * + 3 + 5 = 16 + * should be a multiple of 3.To be divisible by 3, the least value of * should be 2, i.e., 16 + 2 = 18, which is a multiple of 3.∴ * = 2(v) 234117Here, 2+ 3 +4 + * + 1 + 7 = 17 + * should be a multiple of 3.To be divisible by 3, the least value of * should be 1, i.e., 17 + 1 = 18, which is a multiple of 3.∴ * =1 (vi) 621054Here, 6 + * +1 + 0 + 5 + 4 = 16 + * should be a multiple of 3.To be divisible by 3, the least value of * should be 2, i.e., 16 + 2 = 18, which is a multiple of 3.∴ * =2 |
