Test: Number System- 3 - Question 1

Save

In the examination a candidate must get 2/5 marks to pass, out of total marks.Shiyam appeared in the exam ang got 198 marks and still failed by 36 marks.The maximum mark is

A.
560
B.
610
C.
585
D.
480
E.
None of these

Detailed Solution for Test: Number System- 3 - Question 1

Let the maximum mark be M.

Since Shiyam got 198 marks and still failed by 36 marks, this means that Shiyam needed 2/5 of the maximum mark to pass.

Therefore, 2/5 of M is equal to 198 + 36 = 234.

To find M, we can multiply both sides of the equation by 5/2:

M = 234 * 5/2 = 585.

So, the maximum mark is 585.

Detailed Solution for Test: Number System- 3 - Question 2

Let the numerator be x and denominator be y

Fraction will be x/y

According to the question

(x + 4)/y = 1/3

⇒ 3x + 12 = y ......(1)

Now,

x/(y + 3) = 1/6

⇒ 6x = y + 3 ......(2)

Solving both the equations we get

x = 5 and y = 27

So , fraction x/y = 5/27

B.

E.

Detailed Solution for Test: Number System- 3 - Question 7

Let the positive integer be 'x'

Then, 20 times integer = 20x

Square of integer = x²

Twenty times a positive integer is less than its square by 96

x² = 20x + 96

⇒ x² - 20x - 96 = 0

⇒ x²- 24x + 4x - 96 = 0

⇒ x ( x -24) + 4( x - 24) = 0

⇒ (x + 4) × (x -24) = 0

⇒ x = -4, x = 24

∴ The positive integer is 24
