Question

If 20% of a = 10% of b, then b/a equals​

Answer 1

Answer:

b/a = 2

Step-by-step explanation:

First find the value of a and b

find 20% of a = a*20/100

find 10% of b = b*10/100

according to question

20a/100 = 10b/100

a/5 = b/10

a = 5b/10

a = b/2

on putting values of a and b in b/a we get

b/a = b/(b/2)

b/a = 2b/b

b/a = 2

Answer 2

Answer:

2

Step-by-step explanation:

20% of a = 20/100 × a= a/5

10% of b= 10/100 × b=b/10

a/5= b/10

=>5b = 10a

=>b/a=10/5

=>b/a=2
