Question : The sum of three fractions A, B and C, A > B > C, is $\frac{121}{60}$. When C is divided by B, the resulting fraction is $\frac{9}{10}$, which exceeds A by $\frac{3}{20}$. What is the difference between B and C?
Option 1: $\frac{1}{15}$
Option 2: $\frac{1}{10}$
Option 3: $\frac{3}{10}$
Option 4: $\frac{7}{15}$
Correct Answer: $\frac{1}{15}$
Solution : Given: $A + B + C = \frac{121}{60}$ $\frac{C}{B} = \frac{9}{10}$ According to the question, $\frac{9}{10} = A + \frac{3}{20}$ ⇒ $A = \frac{9}{10} - \frac{3}{20} = \frac{18-3}{20} = \frac{15}{20} = \frac{3}{4}$ $B + C = \frac{121}{60} - \frac{3}{4} = \frac{121-45}{60} = \frac{76}{60} = \frac{19}{15}$

Question : If $\triangle ABC \sim \triangle PQR$, AB =4 cm, PQ=6 cm, QR=9 cm and RP =12 cm, then find the perimeter of $\triangle$ ABC.
Option 1: 18 cm
Option 2: 16 cm
Option 3: 20 cm
Option 4: 22 cm
Correct Answer: 18 cm
Solution : $\triangle ABC \sim \triangle PQR$, $\therefore$ $\frac{AB}{BC} = \frac{PQ}{QR}$ And $\frac{AB}{AC} = \frac{PQ}{PR}$ $AB=4$ cm, $PQ=6$ cm, $QR=9$ cm, and $RP=12$ cm ⇒ $\frac{4}{BC} = \frac{6}{9}$ ⇒ $BC = 6$ cm ⇒ $\frac{4}{AC} = \frac{6}{12}$ ⇒ $AC = 8$ cm To find the perimeter
