Answer: Option B

Explanation:

Given That ,

6cd - 3ab = 1

⇒ 3(2cd - ab) = 1

⇒ 2cd - ab = 1/3

another equation is,

ab - 2cd = p

⇒ -1(2cd - ab)= p

⇒ -1/3 = p (putting the value of 2cd - ab)

Ans: P = -1/3

1999 . If an angle of a parallelogram is 60 degrees, find the number of degree of remaining angles.

A. 60, 60, 60
B. 30, 60, 90
C. 60, 120, 120
D. 60, 120, 150

View Answer	Favorite Question	Report

Answer: Option C

Explanation:

Opposite angles of a parallelogram are equal. So, the angle opposite to 60° is also 60°.

Now, sum of the 4 angles is 360°. So, sum of the other two opposite angles is {360 - (60 + 60)} = 360 - 120 = 240°

So, each of the other angles is = 240/2 = 120°.

So, the other three angles are 60°, 120°, 120°.

2008 . If An organization increases its staff salary by 25% . By what percent must it now decrease the salary to return to the original amount ?

A. 15
B. 18
C. 20
D. None of these

View Answer	Favorite Question	Report

Answer: Option C

Explanation:

Let's consider the salary of an officer to be 100.
So, If the salary is increased by 25%, then the new salary - 100 + [100 × (25/100) ] = 100 + 25 = 125
So, his new salary is 125
To make his salary original 25 must be subtracted from 125, then his salary will be 125 - 25 = 100 or original salary.
So, To find the percentage of salary which must be decreased we must find that 25 is what percentage of 125.
So, decrease% = (25/125) × 100 = 1/5 × 100 = 20%
Answer) 20% of his new salary must be deducted so that his salary becomes Original.

Answer: Option B

Explanation:

In an isosceles right triangle, one of the angles is 90 degrees (the right angle), and the other two angles are congruent and each measures 45 degrees.

To find the tangent of angle A (one of the congruent angles), we can use the definition of the tangent function:

tan(A) = Opposite / Adjacent

In this case:

The opposite side to angle A is the side opposite to the 45-degree angle, which is the shorter leg of the right triangle.
The adjacent side to angle A is the side adjacent to angle A, which is also the shorter leg of the right triangle.

Since both the opposite and adjacent sides are the same in an isosceles right triangle, you have:

tan(A) = Opposite / Adjacent = 1 / 1 = 1

So, the tangent of angle A is 1.
