Every prime number of the form 3k + 1 can be represented in the form 6m + 1 (where, k and m are integers), when
Answer: (a)
Every prime number of the form 3k + 1 can be represented in the form 6m + 1 only, when k is even.
If the numbers q, q + 2 and q + 6 are all prime, then what can be the value of 3q + 9?
Answer: (d)
By considering every option
(a) 3q + 9 = 18 ⇒ q = 3
Then, numbers are 3, 5 and 9, which are not all prime.
(b) 3q + 9 = 42 ⇒ q = 11
Then, numbers are 11, 13, 17, which are all prime
(c) 3q + 9 = 60 ⇒ q = 17
Then, numbers are 17, 19 and 23 which are all prime.
Hence, option (d) is correct.
If an amount of Rs 41,910 is distributed equally amongst 22 persons, how much amount would each person get ?
Answer: (c)
Required amount = $41910/22$ = Rs. 1905
If $x = (16^3 + 17^3 + 18^3 + 19^3)$, then x divided by 70 leaves a remainder of
Answer: (c)
Remember that, $a^3 + b^3 = (a + b) (a^2 + b^2 – ab)$
$x = (16^3 + 17^3 + 18^3 + 19^3)$
$x = (16^3 + 19^3) + (17^3 + 18^3)$
$x = (16 + 19) (16^2 + 19^2 – 16 × 19) + (17 + 18) (17^2 + 18^2 – 17 × 18)$
$x = 35[16^2 + 19^2 – 16 × 19 + 17^2 + 18^2 – 17 × 18]$
x = 35 × (Even number)
Hence, x is divisible by 70 and leaves remainder as zero.
