Answer» 1 horse = Rs 11 elephnat = Rs 220 camels = Rs 1 MEANS 1 camel = Rs 0.05.we can form two equations:total NUMBER of animals = 100x+y+z = 100 …………….(1)and total SUM of money = 1001x + 5y + 0.05z = 100 …………(2)by equations (1) and (2)-4y + 0.95z =0.95z = 4yz/y = 4/0.95z/y = 80/19 (after simplification )so if z(camels) = 80 and y(elephants) = 19then horses,x = 100-y-z ( from equation 1)x= 100–80–19x=1now1 horse = Rs 119 elephnats = 19*5= Rs 9580 camels = 80*0.05 = Rs 4 |
