The oceanic crust is primarily composed of mafic rocks, which are rich in silicate and magnesium. This layer is often referred to as 'sima' (silica + magnesium).

Question 5

If (-1/2) * ( x - 5) + 3 = -5/2, then what is the value of x?

Accepted Answer

Subtract 3 from both sides to get (-1/2)(x - 5) = -11/2. Multiply by -2 to get x - 5 = 11, which gives x = 16.

Accepted Answer

The slope of a line through two points is (y2 - y1)/(x2 - x1). Here, (-3 - (-1))/(4 - (-2)) = -2/6 = -1/3. Parallel lines have identical slopes.

Question 8

Arrange the given words in the sequence in which they occur in the dictionary. 1. Xenons 2. Xylyls 3. Xanthic 4. Xenians 5. Xyst 1. Xenons 2. Xylyls 3. Xanthic 4. Xenians 5. Xyst

Accepted Answer

Milk of magnesia is an antacid containing magnesium hydroxide, Mg(OH)2. It is a mild base used to neutralize excess stomach acid and relieve indigestion.

Question 10

If 5 sec θ – 3 tan θ = 5, then what is the value of 5 tan θ – 3 sec θ?

Accepted Answer

Use the identity (a sec θ - b tan θ)² - (a tan θ - b sec θ)² = a² - b². Here, 5² - x² = 5² - 3² = 16, so 25 - x² = 16, giving x² = 9, thus x = 3.

Question 11

In a certain code language, "TREASON" is written as "RKWWINX" and "POULTRY" is written as "CNXHYKT". How is "NUMBER" written in that code language?

Accepted Answer

Let the first term be a and common difference d. We have a+d=8 and a+5d=20. Solving gives d=3 and a=5. The 20th term is a+19d = 5+19(3) = 62.

Question 16

What is the effective discount on two successive discounts of 20% and 25%?

Accepted Answer

Use the successive discount formula: x + y - (xy/100). Here, 20 + 25 - (20 × 25)/100 = 45 - 5 = 40%.

Question 17

If 52 % 32 = 40, 22 % 20 = 4 then what is the value of 15 % 11 = ?

Accepted Answer

The pattern is (First Number - Second Number) × 2. For 52 % 32, (52 - 32) × 2 = 40. Thus, for 15 % 11, (15 - 11) × 2 = 8.

Question 18

What can be said about the two following ratios? I. Loan amount disbursed by Bank 1 in 2011/ Loan amount disbursed by Bank 2 in 2014 II. Loan amount disbursed by Bank 3 in 2014/ Loan amount disbursed by Bank 4 in 2011

Question 19

What is the circumference (in cm) of a circle whose area is 616 sq cm?

Accepted Answer

Area is πr² = 616, so r² = 616 × (7/22) = 196, giving radius r = 14 cm. Circumference is 2πr = 2 × (22/7) × 14 = 88 cm.
