Question : A man borrowed a certain sum of money at the rate of 10% per annum simple interest for the first three years and 15% per annum simple interest for the period beyond three years. If he pays a total interest of INR 2,884.50 at the end of 7 years, then the sum of money (in INR) that he borrowed is:

Question : Three angles of a triangle are $(x-15^{\circ}),(x+45^{\circ}),$ and $(x+60^{\circ})$. Identify the type of triangle.
Option 1: Obtuse angle triangle
Option 2: Right angle triangle
Option 3: Isosceles triangle
Option 4: Equilateral triangle
Correct Answer: Right angle triangle
Solution : Given: Angles of the triangles is $(x-15^{\circ}),(x+45^{\circ}),$ and $(x+60^{\circ})$. Let $\angle A =(x-15^{\circ}) $ $\angle B =(x+45^{\circ}) $ $\angle C =(x+60^{\circ}) $ We know that the sum of the angles of a triangle is $180^\circ$. So, $(x-15^{\circ})+(x+45^{\circ})+(x+60^{\circ}) = 180^{\circ}$ ⇒ $3x+90^{\circ}=180^{\circ}$ ⇒ $x=30^{\circ}$
