Answer 2

Answer:

Required value is 101.027.

Here all options are incorrect.

Step-by-step explanation:

Given,

253:60 :: 426: ?

Here we don't know the fourth proportional.

We need to find it.

But now question is what is the process of finding fourth proportional.

We know,

If a:b::c:d then relation between a,b,c,d is $\frac{a}{b} = \frac{c}{d}$

By one example,we can easily understand the concept.

Let,10:50::20:x

So,$\frac{10}{50} = \frac{20}{x}$

By cross multiplication,

$10 \times x = 20 \times 50$

$x = \frac{50 \times 20}{10} = 100$

So,we can write 10:50::20:100.

Here in the given question

253:60 :: 426: ?

Let required fourth proportional be y.

So,253:60 :: 426: y

$\frac{253}{60} = \frac{426}{y}$

By cross multiplication,

$253 \times y = 426 \times 60$

$y = \frac{426 \times 60}{253} = 2 \times 60 = 101.027$

So, required fourth proportional is 101.027.
