Question
The total of three numbers, A, B, and C, is 2450. The
second number, B, is 4/7 greater than the first number, A. The third number, C, exceeds A by 375. Determine the value of A.Solution
ATQ;
Let A = x
Then B = x + (4/7)x = 11x/7
C = x + 375
Sum: x + (11x/7) + (x + 375) = 2450
Multiplying by 7: 7x + 11x + 7x + 2625 = 17150
25x = 14525
x = 581
