Answer 1

$\huge\bold\red{☆Answer ࿐}$

$prices \: are:-$

$1 \: horse = Rs \: 1$

$1 \: elephnat = Rs \: 2$

$20 \: camels = \\ Rs \: 1 \: means \: 1 \: camel = Rs 0.05.$

$we \: can \: form \: two \: equations:$

$total \: number \: of \: animals = 100$

$x+y+z = 100 ……….(1)$

$and \: total \: sum \: of \: money = 100$

$1x + 5y + 0.05z = 100 ……(2)$

$by \: equations \: (1) \: and \: (2)$

$-4y + 0.95z =0$

$95z = 4y$

$z/y = 4/0.95$

$z/y = 80/19$

$x= 100–80–19$
