Question

the sum of two no. is 2170 .if 2.5 percent of 1 number is equal to 4.5percent of other,find the two numbers. answer is 1395,775.Tell the formula please

Answer 1

let us assume the 2 numbers x and y

x+y =2170......... (1)

X×2.5/100= Y×4.5/100

X×2.5= Y×4.5
y=2.5x/4.5

substitute y value in eqn 1
then we will get
7x = 2170
x= 1395
substitute x value in eqn 1 then we will get y value
775
