of a number A is 22% of a number B. The number B is equal to 2.5% of a third number C. If the value of C is 5500, then the sum of 80% of A and 40% of B is:
Show answer & explanation
Correct answer: D
Explanation

A= B
A = B
= = A:B = 1:10
again,
B = 2.5% of c
B = c
= = B:C = 1:40
⇒ A:B:C = 1 : 10 : 400
Now, 400 unit = 5500
4 unit = 55
1 unit =
then, 80% of A + 40% of B = *
