among 110 students 70 students drink tea and 30 drink coffee and 15 students drink nothing. how many drink tea only.please I nee
1 answer:
Answer:
65
Step by step explanation:
If 15 students drink nothing, the total of students who drink is 110-15=95.
Out of this 95, 70 drink tea and 30 drink coffee. 70+30=100 but there are only 95 students who drink so that must mean that 5 students (100-95=5) drink both. So you have to subtract five from botht the group of tea drinkers and coffee drinkers (65+5+25=95)
