When 32% of a number X was added to another number y , then y increases by 24%. The value of (2x+y)/(3x+y) is:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 2.
32% of x = 32x/100 = 0.32x
24% of y = 24y/100 = 0.24t
ATQ -
0.32x + y = 1.24y
0.32x = 0.24y
x/y = 0.24/0.32
x/y = 3/4
Required value = (2x + y)/(3x - y)
Substituting value of x = 3 and y = 4
(2x + y)/(3x + y) = [2(3) + 4]/[3(3) - 4] = (6 + 4)/(9 - 4) = 10/5 = 2
