Question

यदि a'का 20% = b हैं तो 20 का b % कितना होगा ?
A.a का 4% B.a का 6%
IC.a का 8% D.a का 10%​

Answer 1

Step-by-step explanation:

let a = 100

20% of 100 = 1/5 *100 = 20 (which is b)

b% of 20 = ?

20 % of 20 = 20 × 20/100 = 4

4 is 4% of 100 (which is a)

therefore,

b% of 20 = 4 % of a Answer

option(A) is correct
