First you need to divide ₹134 by 12 to find the cost of each pen.

Multiply the cost of each pen by 5 to find the cost of 5 pens.

≈ ₹55.8 (correct to 1 decimal place)
Answer:
Option D.
Step-by-step explanation:
If two triangles ΔABC and ΔA'B'C' are similar then we take point C of ΔABC to find the transformation performed form C to C'.
Coordinates of C are (0, 3) and the coordinates of C' are (0, -1).
This shows that C is rotated 180° about origin to get the new coordinates as (0, -3) and then new coordinates were dilated by 1/3 which forms C' as (0, -1)
Therefore option D is the correct option.
