Question

A photocopier is making reduced copies of a photo that measures

Answer 1

Answer:

The height of First Copy is 20 cm.

Step-by-step explanation:

Given:

Original Height = 25 cm

First copy is reduce to 80% of Original height.

Therefore to find the height of first copy can be find out by multiplying 80 with original height and then dividing by 100.

∴ Height of First Copy = $\frac{80}{100} \times \textrm{original height}= 0.8\times 25 cm = 20cm$

Hence Height of first copy is 20 cm

Now Another copy is reduce to 85% of First Copy.

Therefore to find the height of another copy can be find out by multiplying 85 with first copy height and then dividing by 100.

∴ Height of Another Copy = $\frac{85}{100} \times \textrm{first copy height}= 0.85\times 20 cm = 17cm$

Hence Height of Another copy is 17 cm
