Question

Pratham enlarges an image of dimensions 37.5cm*25cm on his computer in such a way that the dimensions of the enlarged image are in same proportion as the orginal image. Which of these could be the dimensions of the new enlarged image? Options a)60cm*40cm b)75cm*62.5cm c)75cm*75cm d)100cm*50cm

Answer 1

Answer:

a

Step-by-step explanation:

In the original image, when you divide the length by the width, you get

37.5/25= 1.5

Now even when the picture has enlarged , this ratio of length to width will never change as the question says ''the dimensions of the enlarged image are in same proportion as the orginal image'' .

So for each part, calculate this ratio, and the one which results in 1.5 will be the dimensions of the enlarged image

a) 60/40    = 1.5  <----the ratio is 1.5 here

b) 75/62.5 = 1.2

c) 75/75     =1

d) 100/50  = 2

therefore a) is the answer

Answer 2

Answer:

easy

Step-by-step explanation:

60/40=1.5
