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) What percent is a of (b + c + d)? |
|
A. 14.28% |
|
|
B. 25% |
|
|
C. 33.33% |
|
|
D. 10% |
From statement (iv), we can get, c + d = 100
Putting the value of c + d in (i), we get, a = 40
Putting a = 40 in (ii) we get, b = 20
a / b+c+d x 100 = 40/120 =33.33%;
