one number is 4 times a first number. a third number is 100 more thann the first number. if the sum of the three numbers is 562,
Anuta_ua [19.1K]

The numbers are 77 , 177 and 308 .

Numbers are the building blocks in mathematics. It is an arithmetic value that is used to represent a quantity. Real numbers , integers , natural numbers, whole numbers , irrational numbers are are various types of numbers.

Let us consider the first number to be x . Then the second number is 4x+100 , and the third number is 100 more than the first number. Therefore the the sum of the three numbers will be:

x+4x+(x+100)=6x+100

Now the sum of all the numbers is 562.

Therefore we can write a linear equation in x to find the values of x.

∴ 6x+100=562

or, 6x = 562 - 100

or, 6x = 462

or, x = 462 ÷ 6

or, x = 77

Therefore the second number is 4x = 4 × 77 = 308 and the third number is x + 100 = 77 + 100 = 177 .

So the numbers are 77 , 177 and 308 .
