Four numbers have a sum of 9900. The second exceeds the first by 1/7 of the first. The third exceeds the sum of the first two by
Amanda [17]

Answer:

1050, 1200, 2550 and  5100.

Step-by-step explanation:

If the first number is x then the second is  x + 1/7x.

The third =  x + x + 1/7x + 300 and the fourth = x + x + 1/7x + x + x + 1/7x+ 300 + 300.

So our equation is:-

8x +  4 * 1/7x  + 900 = 9900

60/7 = 9000

60x = 7*9000

x = 1050.

Therefore the 4 numbers are 1050,  *1/7*1050 = 1200, 2550 and  5100.
