1.	Marks each)ayng as(12)9) times square root of total number of elephantsin the lake come to the bank. While two elephantsare playing in water and have not come to thebank, then what is the number of elephants ?(Number of elephants is a positive integer)
Answer» Let the total no. of elephants = xNo. of elephants on the bank = 7/2 √xRemaining elephants= 2A/Q x=7/2 √x+2x-2 = 7/2 √x2(x-2) = 7√x4(x-2)² = 49x4(x²-4x+4) = 49x4x²-65+16 = 0(x-16) (4x -1) = 0x-16 = 0 or 4x-1 = 0x = 16 or x = 1/4Since, the no. of elephants cannot be 1/4∴ x = 16The total no.of elephants = 16
