a യുടെ b% ത്തിന്റെയും b യുടെ a% ത്തിന്റെയും തുക ab യുടെ എത്ര ശതമാനമാണ് ?

Aa+b

Ba-b

Cab

D2

Answer:

D. 2

Read Explanation:

Let's break it down:

a% of b = (a/100) × b
b% of a = (b/100) × a

The sum of these two expressions:

(a/100) × b + (b/100) × a
= (ab/100) + (ab/100)
= 2ab/100

To find the percentage of ab:

(2ab/100) / ab × 100%
= 2%

So, the sum of a% of b and b% of a is 2% of ab.
