The sum of x, y coordinate values is 2490. if 6.5% of one coordinate is equal to 8.5% of the other, then the coordinate values are :
Answer/Solution
1411,1079
Steps/Work
Explanation :
Solution: Let the coordinates be x and y. then, 6.5% of x = 8.5% of y
=> x = 85/65
y = 17/13 y
Now, x+y =249017y/13+y = 2490
=> 30y/13 = 2490
=> y = 2490*13/30 = 1079.
.'. One coordinate is = y= 1079, other coordinate = 17y/13 =1411
Answer : D
