Answer 2

We have:

534 : 60 : : 551 : ?

We have to find, the value of next number in the proportion.

Solution:

We know that,

If a, b, c and d are in the proportion.

a : b : : c : d

⇒ a × d = b × c

∴ 534 : 60 : : 551 : ?

⇒ 534 × ? = 60 × 551

⇒ ? = $\dfrac{ 60 \times 551}{534}$

⇒ ? = $\dfrac{ 10 \times 551}{89}$

⇒ ? = $\dfrac{5510}{89}$

∴ The next number in the proportion = $\dfrac{5510}{89}$

Thus, the next number in the proportion is $\dfrac{5510}{89}$.
