Question : A merchant changed his trade discount from 25% to 15%. This would increase his selling price by:
Option 1: $3\frac{1}{3}$%
Option 2: $6\frac{1}{6}$%
Option 3: $13\frac{1}{3}$%
Option 4: $16\frac{1}{3}$%
Correct Answer: $13\frac{1}{3}$%
Solution : Given: A merchant changed his trade discount from 25% to 15%. Let the marked price be Rs. 100. Now for a 25% discount the selling price is = (100 – 25) = Rs. 75 and for a 15% discount, the selling price is = (100
Question : In an isosceles triangle $ABC$, $AB = AC$ and $\angle A = 80^\circ$. The bisector of $\angle B$ and $\angle C$ meet at $D$. The $\angle BDC$ is equal to:
Option 1: $90^\circ$
Option 2: $100^\circ$
Option 3: $130^\circ$
Option 4: $80^\circ$
Correct Answer: $130^\circ$
Solution : Given: $ABC$ is an isosceles triangle and $AB = AC$. Let $\angle B=\angle C=x$ $\angle A+\angle B+\angle C = 180^\circ$ ⇒ $80^\circ+x+x = 180^\circ$ ⇒ $2x = 180^\circ-80^\circ$ ⇒ $2x = 100^\circ$ ⇒ $x = 50^\circ$ So, $\angle B = \angle C = 50^\circ$ The
