Question

when a heart is broken the ratio of it's feeling is 1:2:3:4.the cost of heart is directly proportional to the square of number of feelings. There is A loss of rs 700 on broken heart,. Find the initial cost of heart.?

Answer 1

$\huge\star\underline\mathfrak\green{Answer:-}$

let feelings are 1x+2x+3x= 6x

actual cost of = 36x^2

and cost of after breaking heart , = 1x^2+ 4x^2+ 9x^2= 14x^2

loss of = (36-14) x^2 =22x^2 = 1320

x^2= 1320/22=60. then

actual cost of = 36x^2 = 36×60 = 2160

$\huge \mathcal {\fcolorbox{red}{gray}{\green{A}\pink{N}\orange{S}\purple{W}\red{E}\blue{R}}}$

let feelings are 1x+2x+3x= 6x

actual cost of = 36x²

and cost of after breaking heart , = 1x²+ 4x²+ 9x²= 14x²

loss of = (36-14) x² =22x²= 1320

x²= 1320/22=60. then

actual cost of = 36x² = 36×60 = 2160
