Question

A florist has W white roses and R red roses. He doesn't have roses of any other color. 3/10 of the red roses got sold .

Which of these equations gives us the number of roses left in the shop ?
a, W+R
b, W+3/10R
c, W+7/10R
d, 7/10(W+R)

Answer 1

Answer:

option c

Step-by-step explanation:

number of R red roses left in the shop

is 1 - 3r/10 = 7r/10

hence, total no. of roses in the shop = W + 7R/10

Answer 2

Given,

Number of white roses = W

Number of red roses = R

The portion of red roses sold = 3/10

To find,

Number of roses left in the shop

Solution,

Total number of roses initially present = W + R

Total number of roses present now = W + (3/10)R

Thus the correct option is B = W+(3/10)R
