The price of an article is increased from Rs 75 to Rs 78. Find the percentage increase in the price of the article. WITH FULL CALCULATION PLEASE

Work Shown:

A = old value = 75

B = new value = 78

C = percent change

C = [ (B-A)/A ] * 100%

C = [ (78-75)/75 ] * 100%

C = (3/75) * 100%

C = 0.04 * 100%

C = 4%

The positive C value means we have a percent increase.

The price has increased by 4%

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
