S3. Ans.(b)
Sol. A number is divisible by 9 if the sum of its digits is divisible by 9. Let the number be x.
∴ 5 + 4 + 3 + 2 + x + 7 = 21 + x
If we put x = 6, then it is divisible by 9.
∴ x = 6
Hence, the digit in place of * is 6.
S4. Ans.(d)
Sol. A number is divisible by 11, if the difference of the sum of its digits at odd places and the sum of its digit of even places, is either 0 or a number divisible by 11.
∴ (5 + 9 + * + 7) – (4 + 3 + 8) = 0
Or multiple of 11
⇒ (21 + *) – 15 = 0 or multiple of 11.
⇒ 6 + * = 0 or multiple of 11.
⇒ * + 6 = a multiple of 11.
⇒ * + 6 = 11
⇒ * = 5
S5. Ans.(a)
Sol. Here, 280 is a multiple of 35.
∴ Required remainder = Remainder obtained on dividing 115 by 35 = 10
S6. Ans.(d)
Sol. Given, n(n + 1) (n + 2)
Now, putting n = 1, we have 
1 (1 + 1) (1 + 2) = 1 × 2 × 3 = 6
