Q. |
If a, b, c, d are positive integers. Solve the question with the 4 statements given below. i) a % of (c + d) = 40 ii) a – b = 20 iii) b + c = 50 iv) a + b = (c + d)% of (a + b) To get the answer to find the percentage a of (b + c + d), which of the above statement is not required? |
|
A. (i) |
|
|
B. (ii) |
|
|
C. (iii) |
|
|
D. (iv) |
From statement (iv), we can get, c + d = 100
Putting the value of c + d in (i), we get, a = 40
a / b+c+d x 100 = 40/120 =33.33%
We don't need statement (iii) to get the above answer.
