Question 9

If sec2 θ + tan2 θ = 5/3, then what is the value of tan 2θ?

Accepted Answer

Substitute sec²θ = 1 + tan²θ to get 1 + 2tan²θ = 5/3. Solving gives tanθ = 1/√3, so θ = 30°. Thus, tan 2θ = tan 60° = √3.

Question 10

Which of the following is not true about a Demand Draft?

Accepted Answer

A Demand Draft is a prepaid instrument where the bank guarantees payment. Unlike a regular cheque, it cannot bounce or be dishonoured due to insufficient funds.

Question 11

In the following question, select the odd letter pair from the given alternatives.

Accepted Answer

The sum of the positional values of the first two letters equals the third letter. B(2)+N(14)=P(16). But G(7)+I(9)=16(P), not R(18).

Question 12

If 'A + B' means 'A is father of B', 'A – B' means 'A is mother of B', 'A * B' means 'A is brother of B' and 'A % B' means 'A is sister of B', then how is Q related to S in 'P + Q * R – S'?

Accepted Answer

In 'P + Q * R - S', Q * R means Q is R's brother, and R - S means R is S's mother. Therefore, Q is the brother of S's mother, making Q the maternal uncle of S.

Question 14

What is the simpliﬁed value of 1 + tan A tan (A/2)?

Accepted Answer

Convert to half-angles: let t = tan(A/2). The expression becomes 1 + [2t/(1-t²)] × t = (1+t²)/(1-t²). This is the exact formula for 1/cos A, which equals sec A.

Question 15

Which base is present in lime water?

Accepted Answer

Lime water is the common name for a dilute aqueous solution of calcium hydroxide, Ca(OH)2. It is prepared by stirring calcium hydroxide in pure water and filtering off the excess.
