Half the number of students of the first school, two-thirds of the second, three-fourth of the third and four-fifths of the fourth are all equal. What is the ratio of the number of students of A to D, if A, B, C and D be the first, second, third and fourth schools,respectively?

• A. 8 : 5
• B. 1 : 3
• C. 2 : 3
• D. 7 : 9

Answer 1

Answer: (A)

8 : 5

Answer 2

Given,

Total number of students in 4 schools of a city = 43,800 and

$\frac{1}{2}(A)=\frac{2}{3}(B)=\frac{3}{4}(c)=\frac{4}{5}(c)$

$A:B=4:3$ and

$B:D=6:5$

Now, $A:B:D=8:6:5$

$A:D=8:5$

Hence, option A is the correct answer.The correct option is (A): 8 : 5
