Question

The winery sold 81 cases of wine this week. If twice

as many red cases were sold than white, how many
white cases were sold this week?


A. 32 cases
B. 61 cases
C. 27 cases
D. 54 cases​

Answer 1

Option (C)

Explanation:

Let the red cases sold = r

and the number of white cases sold = w

Total number of cases sold by the winery = 81

r + w = 81 -------(1)

If number of red cases sold is twice of white cases sold,

r = 2w ------- (2)

By substituting the value of r from equation (2) to equation (1),

2w + w = 81

3w = 81

w = 27 cases

From equation (1),

r + 27 = 81

r = 54 cases

Therefore, number of white cases sold are 27 cases

Option (C) is he answer.
