Question

 10% of A is equal to 20% of B. If the value of B is 140 what is the value of A.? ​

Answer 1

Answer:

280

Step-by-step explanation:

(10/100)A = (20/100)B

A = 2B.

B = 140

=> A = 2*140 = 280.

Answer 2

Answer:

280

Step-by-step explanation:

$\frac{20}{100} \times b = \frac{10}{100} \times a$

Given that B=140

$\frac{2}{10} \times 140 = \frac{1}{10} \times a$

a=2 x 140

a=280
