What is the ratio of the total number of donuts sold by stores P and R together in October to the total number of donuts sold by stores Q and R together in the same month ?
Answer & explanation
Correct answer: option 2
Number of donuts sold by P & R in october = 125 + 960 = 1085
Number of donuts sold by Q & R in october = 905 + 960 = 1865
Required ratio = 1085 : 1865
= 217 : 373
