Question : A shopkeeper earns a profit of 15% after selling a book at a 20% discount on the printed price. The ratio of the cost price to the printed price of the book is:
Option 1: 20 : 23
Option 2: 23 : 20
Option 3: 16 : 23
Option 4: 23 : 16
Correct Answer: 16 : 23
Solution : Selling price = $\frac{100-\text{discount%}}{100}×$ marked price Selling price = $\frac{100+ \text{profit%}}{100}×$ cost price From both formulas, $\frac{100-\text{discount%}}{100}×$ marked price = $\frac{100+ \text{profit%}}{100}×$ cost price ⇒ $\frac{100-20}{100}×$ marked price = $\frac{100+15}{100}×$ cost price ⇒ Cost price : marked price = 80 : 115 =
Question : The length of the side of a cube is 2.8 cm. What is the volume of the largest sphere that can be taken out of the cube?

Option 4: 115 cm3
Correct Answer: 11.50 cm3
Solution : The length of the side of a cube = 2.8 cm. The diameter of the largest sphere that can be taken out of the cube = 2.8 cm So, required radius = 1.4 cm Volume of sphere = $\frac{4}{3}\pi r^3$ = $\frac{4}{3}\times \frac{22}{7}\times

Option 3: $A = B - C$
Option 4: $A=\frac{B-C}{2}$
Correct Answer: $A = B + C$
Solution : Given, $\tan A-\tan B-\tan C=\tan A \tan B \tan C$ ⇒ $\tan A - \tan A \tan B \tan C = \tan B + \tan C$ ⇒ $\tan A(1-\tan B \tan C)= \tan B + \tan C$ ⇒ $\tan A =

Question : A rectangular park is 120 m long and 104 m wide. A 1-m wide path runs along the boundary of the park, remaining completely inside the park area. Thus, the outside edges of the path run along the boundary wall of the park. The inside edges of the path are marked with a white line of negligible thickness. If it costs INR 2.50 to mark each metre with the white line, then how much would it cost (in INR) to fully mark the inside edges of the path?
Option 1: 1090
Option 2: 1080
Option 3: 1120
Option 4: 1100
Correct Answer: 1100
Solution : Given: A rectangular park is 120 m long and 104 m wide. A 1-m wide path runs along the boundary of the park, remaining completely inside the park area. Length of the park without the path = (120 – 1 – 1) = 118 m
