In a certain coffee shop, the ratio of orders for coffee, tea, and water is 5:6:10. In the afternoon, the ratio of orders for coffee to tea tripled and the ratio of orders for coffee to water halved. What is the minimum number of coffee orders that could have been made in the afternoon ?

A. 1
B. 2
C. 4
D. 5
E. 6

C:T:W $$= 5:6:20$$

In afternoon , C:T $$= 15:6$$ and C:W $$=5:20$$

Equating coffee we have, C:W $$= 15:60$$

Final ratio $$15:6:60$$

Since all numbers need to be integers we can reduce by $$3$$ to get $$5:2:20$$

Minimum Coffee $$= 5$$

Ans D

Hope it's clear
