Question

17:52::1:....
a)3 b)4 c)5 d)51

Answer 1

Step-by-step explanation:

17 : 52 : : 1 : 3

Solution:

Given that,

17 : 52 : : 1 : ?

We have to find the fourth term

If a : b : : c : d or in other words a : b = c : d, then the quantity 'd' is called fourth proportional to a, b and c

When a : b : : c : d then we can say,

\frac{a}{b} = \frac{c}{d}

b

a

=

d

c

So the given first three terms are:

Let the fourth term be x

17 : 52 : : 1 : x

\frac{17}{52} = \frac{1}{x}

52

17

=

x

1

\begin{gathered}17x = 52\\\\x = 3.05 \approx 3\end{gathered}

17x=52

x=3.05≈3

Thus the fourth term is 3
