Question : If $3 \sin x+4 \cos x=2$, then the value of $3 \cos x – 4 \sin x$ is equal to:
Option 1: $\sqrt{23}$
Option 2: $\sqrt{21}$
Option 3: $\sqrt{29}$
Option 4: $21$
Correct Answer: $\sqrt{21}$
Solution : Given: $3 \sin x+4 \cos x=2$ (equation 1) Let $3 \cos x–4 \sin x=k$ (equation 2) We know the trigonometric identity, $\sin^2 x+ \cos^2 x=1$. Squaring the equation and adding them together, $(3 \cos x–4 \sin x)^2+(3 \sin x+4 \cos x)^2=k^2+2^2$ ⇒ $9 \cos^2 x+16

Question : The monthly salary of a person was INR 1,60,000. He used to spend on three heads - Personal and family expenses (P), Taxes ( T ) and Education loans (E). The rest were his savings. P was 50% of the income, E was 20% of P, and T was 15% of E. When his salary got raised by 30%, he maintained the percentage level of P, but E became 30% of P and T became 20% of E. The sum of the two savings (in INR) is:
Option 1: 2,11,680
Option 2: 1,28,160
Option 3: 1,18,620
Option 4: 1,62,810
Correct Answer: 1,28,160
Solution : Given: The monthly salary of a person = INR 1,60,000 Personal and family expenses are denoted as (P) Taxes are denoted as (T) Education loan is denoted as (E) According to the question, 1st condition: P = $160000 × \frac{1}{2}$ = 80000 E = $80000

Question : A works 3.5 times as fast as B, and A takes 45 days less than B to complete a job when each works alone. Calculate the number of days taken to complete the same job if A and B work together.
Option 1: 10.5
Option 2: 17.5
Option 3: 21
Option 4: 14
Correct Answer: 14
Solution : The ratio of the number of days A and B take to complete the work alone is in the inverse ratio of their efficiencies. $\therefore$ The ratio of the number of days taken by A and B $ = 1 : 3.5$ Let the number
Question : Direction: In the following question, select the related number from the given alternatives.
82 : 06 :: 76 : ?
Option 1: 15
Option 2: 01
Option 3: 12
Option 4: 24
Correct Answer: 01
Solution : Given:
The pattern followed is –
82 → 8 – 2 = 6
