Question : If $\triangle A B C \sim \triangle F D E$ such that $A B=9 \mathrm{~cm}, A C=11 \mathrm{~cm}, D F=16 \mathrm{~cm}$ and $D E=12 \mathrm{~cm}$, then the length of $BC$ is:
Option 1: $5 \frac{3}{4} \mathrm{~cm}$
Option 2: $4\frac{3}{5} \mathrm{~cm}$
Option 3: $3\frac{5}{7} \mathrm{~cm}$
Option 4: $6\frac{3}{4} \mathrm{~cm}$
Correct Answer: $6\frac{3}{4} \mathrm{~cm}$
Solution : Given: $A B=9 \mathrm{~cm}, A C=11 \mathrm{~cm}, D F=16 \mathrm{~cm}$ and $D E=12 \mathrm{~cm}$ $\triangle ABC \sim \triangle FDE$ Now, $\frac{AB}{DF}= \frac{BC}{DE}$ Substituting the given values: ⇒ $\frac{9}{16}= \frac{BC}{12}$ $⇒BC = 12 \times \frac{9}{16} = 6\frac{3}{4} \mathrm{~cm}$ Hence, the correct answer is $6\frac{3}{4} \mathrm{~cm}$.

Yes, it's possible to change your stream after 12th and do arts in college. Many students switch streams based on their interests, preference and career goals. If you are interested in doing arts and want to explore that field, you can definitely make the switch in the career Just
I understand it can be really confusing but if you have completed your BSc with Physics, Chemistry, and Maths then you can apply for AFCAT (non-technical) under the "Graduate" category. So the correct option from the various options would be "Graduate C."
Hope this helps,
Thank you
