Question

old ratio 3:1 ; new ratio ; 3:2:2. Calculate sacrificing ratio

Answer 1

if old ratio A:B =3:1 and new ratio A:B:C=3:2:2
then sacrificing ratio-
A= 3/7-3/4= -9/28 (sacrifice)
B=2/7-1/4=1/28 (gain)
C= 2/7=8/28 (gain)

Answer 2

$\huge\mathbb\orange{AnSwEr:-}$

To calculate Sacrificing ratio:-

Old ratio- New ratio

$= old \: ratio = 3 : 1 \\ new \: ratio = 3 : 2 : 2 \\ sacrificing \: ratio \: of \: first \: partner = \\ = \frac{3}{4} - \frac{3}{7} = \frac{21 - 12}{24} = \frac{9}{24} = \frac{3}{8} \\ Sacrificing \: ratio \: of \: second \: partner = \\ = \frac{1}{4} - \frac{2}{7} = \frac{8 - 7}{24} = \frac{1}{24} = \frac{1}{8} \\ so \: sacrificing \: ratio \: is \: 3 :1 \\ ie \: old \: ratio \: and \: sacrificing \: ratio \: is \: equal$

hope this helps..
