Question

If 5/8=20/p,then value of p is (A) 23 (B) 2 (C) 32 (D) 16

Answer 1

solution

5/8=20/p

first we cross multiply the equation

⇒ 5*p=8*20

⇒5p=160

then we divided booth side by 5

⇒p=32

then the correct answer is (c)

Answer 2

Given:

$\dfrac{5}{8}=\dfrac{20}{p}$

We have to find, the value of p is:

Solution:

∴ $\dfrac{5}{8}=\dfrac{20}{p}$

By cross-multiplication, we get

5 × p = 20 × 8

⇒ 5p = 160

⇒ p = $\dfrac{160}{5}$

⇒ p = 32

∴ p = 30

Thus, the value of "p option C) 32" is correct.
