Question

two numbers in a ratio of 4:5 and their product is 8820 then find the sum of two numbers??

Answer 1

let the numbers be 4 x and 5 x
4 x *5 x = 8820
20 x^2 = 8820
x^2 =441
x is equal to 21
4 x = 84
5 x =105
4 x + 5 x = 84 + 105
4 x + 5 x = 189

Answer 2

Hey dear your answer is here.

let the number of the ratio be 4x.
And the other number of the ratio be 5x.

Sum of two rational numbers = 8820

ATQ,
4x + 5x = 8820
9x =8820
x =8820÷9
x = 980

Therefore, 4x = 4 * 980
= 3920

And, 5x = 5*980
= 4900
