Question

out of a group of a swans of times the square root
of no. of swams are playing in the shower of the tank remaining two are quarilling in the water
calculate the toal no. of swans.​

Answer 1

Answer:

Let the total no. of swans = x

No. of swans playing on the shore = 7/2 √x

Remaining swans = 2

A/Q x=7/2 √x+2

x-2 = 7/2 √x

2(x-2) = 7√x

4(x-2)² = 49x

4(x²-4x+4) = 49x

4x²-65+16 = 0

(x-16) (4x -1) = 0

x-16 = 0 or 4x-1 = 0

x = 16 or x = 1/4

Since, the no. of swans cannot be 1/4

∴ x = 16

The total no.of swans = 16
