Assume that 20 cows and 40 goats can be kept for 10 days for Rs.460. If the cost of keeping 5 goats is the same as the cost of keeping 1 cow, what will be the cost for keeping 50 cows and 30 goats for 12 days?	Pick:
A) Rs.1104
B) Rs.1000
C) Rs.934
D) Rs.1210
E) Rs.1110
Rs.1104ssume that cost of keeping a cow for 1 day = c ,   cost of keeping a goat for 1 day = g   Cost of keeping 20 cows and 40 goats for 10 days = 460   Cost of keeping 20 cows and 40 goats for 1 day = 460/10=

46= 20c + 40g = 46   = 10c + 20g = 23 ---(1)   Given that 5g = c   Hence equation (1) can be written as 10c + 4c = 23 =14c =23   = c=23/14   cost of keeping 50 cows and 30 goats for 1 day   = 50c + 30g   = 50c + 6c (substituted 5g = c)   = 56 c = 56×23/14   = 92   Cost of keeping 50 cows and 30 goats for 12 days = 12×92 = 1104 Rs.1104NSWER : Rs.1104
