Which digits should come in place of * and # if the number 62684*# is divisible by both 8 and 5?
Answer: (c)
Since the given number is divisible by 5, so 0 or 5 must come in place of #.
But, a number ending with 5 is never divisible by 8.
So, 0 will replace #.
Now, the number formed by the last three digits is 4*0,
which becomes divisible by 8, if * is replaced by 4.
Hence, digits in place of * and # are 4 and 0 respectively.
‘A’, ‘B’ and ‘C’ are three consecutive even integers such that four times ‘A’ is equal to three times ‘C’. What is the value of B ?
Answer: (d)
Let A = x,
B = x + 2,
C = x + 4
∴ According to the question
4x = 3(x + 4)
⇒ 4x – 3x = 12 ⇒ x = 12
∴ B = x + 2 = 12 + 2 = 14
The product of two successive numbers is 8556. What is the smaller number?
Answer: (d)
Let the numbers be x and (x + 1),
∴ x(x + 1) = 8556
or, $x^2 + x – 8556 = 0$
or, $x^2 + 93x – 92 x – 8556 = 0$
or, $(x^2 + 93) (x – 92) = 0$
∴ x = 92
What is the number of terms in the series 117, 120, 123, 126,.............., 333 ?
Answer: (c)
117, 120, 123, 126, ........., 333
Given series is an A.P series with
first term, a = 117,
last term l =333
and common difference, d = 3
last term, l = a + (n – 1)d
where, n = number of terms.
117 + (n – 1)3 = 333
(n – 1)3 = 216 ⇒ n = 73
