Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following set. (6, 22, 14); (8, 30, 19) (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Question : A, B, and C are three angles of a triangle. If $A-B=45^{\circ}$ and $B-C=15^{\circ}$ then $\angle A=$?
Option 1: 83°
Option 2: 85°
Option 3: 95°
Option 4: 75°
Correct Answer: 95°
Solution : Given, $A-B=45^{\circ}$ And $B-C=15^{\circ}$ So, $A=45^{\circ}+B$ And, $C=B-15^{\circ}$ By the angle sum property of a triangle, $A+B+C=180^\circ$ ⇒ $45^{\circ}+B+B+B-15^{\circ}=180^{\circ}$ ⇒ $3B+30^\circ = 180^\circ$ ⇒ $B = 50^\circ$ Now, $A=45^{\circ}+B= 45^{\circ}+50^\circ= 95^\circ$ Hence, the correct answer is $95^\circ$
