Question

if l and m are in indirect variation and l.m =20 , then find m for l= 5​

Answer 1

Answer:

$l \: \alpha \frac{1}{m} \\ l \: = \frac{x}{m} \\ = > lm = x \\ x = 20. \\ so \: l = \frac{20}{m} \\ put \: l \: = 5 \\ 5 = \frac{20}{m} \\ m = 4$

Answer 2

Answer:

4

Step-by-step explanation:

Given,

l.m = 20

l = 5

To find : m = ?

l.m = 20

l × m = 20

5 × m = 20

m = 20 / 5

m = 4
