Question : Two numbers are, respectively, 17% and 50% more than a third number. The ratio of the two numbers is:
Option 1: 27 : 25
Option 2: 39 : 50
Option 3: 19 : 11
Option 4: 29 : 25
Correct Answer: 39 : 50
Solution : Let the third number be 100. According to the question, the first number will be 117 and the second number will be 150. So, the required ratio = 117 : 150 = 39 : 50. Hence, the correct answer is 39 : 50.
Question : Which of the following is equal to $\sec A – \cos A$?
Option 1: $\sin A\cot A$
Option 2: $\cot A\ cos A$
Option 3: $\tan A\sin A$
Option 4: $\cos A\sin A$
Correct Answer: $\tan A\sin A$
Solution : Given: The trigonometric expression is $\sec A – \cos A$. We know the trigonometric identity $1–\cos^2 A= \sin^2 A$. ⇒ $\sec A – \cos A$ $=\frac{1}{\cos A}–\cos A$ $=\frac{1–\cos^2 A}{\cos A}$ $=\frac{\sin^2 A}{\cos A}$ $=\frac{\sin A}{\cos A}\times \sin A=\tan A\sin A$ Hence, the

Question : If the angle of a right-angled triangle is 35°, then find the other angles.
Option 1: 90° and 75°
Option 2: 90° and 35°
Option 3: 90° and 55°
Option 4: 90° and 45°
Correct Answer: 90° and 55°
Solution : Let ABC be a triangle right-angled at B. Let $\angle$ A = 35° By angle sum property in $\triangle$ ABC, $\angle$A + $\angle$B+$\angle$C = 180° ⇒ 35° + 90° + $\angle$C = 180° ⇒ $\angle$C = 55° Hence, the correct answer is 90°
