a) 5 : 2
b) 7 : 5
c) 5 : 7
d) 2 : 5
correct answer is : d) 2 : 5
Explanation
Here, A : B = 5 : 8
\therefore\ \frac{A}{B}\ =\ \frac{5}{8}
And, B : C = 16 : 25
\therefore\ \frac{B}{C}\ =\ \frac{16}{25}
So, \frac{A}{B}\ \times\ \frac{B}{C}\ =\ \frac{5}{8}\ \times\ \frac{16}{25}
\therefore\ \frac{A}{C}\ =\ \frac{2}{5}
\therefore A : C = 2 : 5
Ans: A : C = 2 : 5
