Question

The sum of three numbers is 900, if the sum of two of those numbers is 545, what is the third number. (Solve with bar model)​

Answer 1

Answer:

let three number be x, y  ,z  so that,

x + y + z=900 ... (1)

again by question,

x + y = 545...(2)

now, combining eqn (1) and (2) we get,

545 + z=900

z=900-545

z=355

which is the required value of third number
