Hi dear, here is your answer
Let the numbers be 3x, 2x and 5x.
Then,
9x + 4x + 25x =1862
⇒ 38x = 1862
⇒ x = 49 ⇒ x = 7.
middle number = 2x = 14.
Then,
9x + 4x + 25x =1862
⇒ 38x = 1862
⇒ x = 49 ⇒ x = 7.
middle number = 2x = 14.
thank you...

let the nos. be 3x, 2x, 5x (as they are in ratio)their square will be: 9x², 4x², 25x²
now according to the ques,
9x²+4x²+25x²=1862
38x²=1862
x²= 49
x=√49
x = 7 Ans.
