Question

Solve 987:168::837:?

Answer 1

Answer:

Step-by-step explanation:

a:b::c:d

as we know

a x d = b x c

so

987 x d = 168 x 837

987 d= 140616

d = 142.5

Answer 2

Answer:

987 : 168 :: 837 : 142.5

Step-by-step explanation:

Given 987 : 168 :: 837 : ?

Let us take ? = x

then 987 : 168 :: 837 : x

We know that a : b :: c: d

That is $\frac{a}{b} =\frac{c}{d}$

Now cross multiplying the above expression, then

⇒ a × d = b × c

987 : 168 :: 837 : x

$\frac{987}{168} = \frac{837}{x}$

Now cross multiplying the above expression, then

⇒ 987 × x = 837 ×168

⇒ 987 × x = 140,616

⇒ x = $\frac{140616}{987}$

∴ x = 142.46 ≈ 142.5

Therefore, 987 : 168 :: 837 : 142.5
