One hundred monkeys have 100 apples to divide. Each adult gets three apples while three children share one. The number of adult monkeys is_____.

• A. 20
• B. 25
• C. 30
• D. 33

Answer 1

The correct option is B 25

Number of apples=100
1 adult get 3 apples
3 children get 1 apple
Ratio of adult and children get apple$=3:1=3+1=4$
Number of apples for adult=$\frac{3}{4}\times 100=75$
3 apple for 1 adult
75 apple for $\frac{75}{3}=25$
Hence, number of adult monkey is 25
