Question

there are some Lotus flowers in a lake if one butterfly sits on each flower and butterfly is left if two butterfly sit on each flower one flower is left what is the number of flowers and butterflies ​

Answer 1

Answer:

4 & 3

Step-by-step explanation:

Assume

the number of butterflies = x

the number of flowers = y

Given that if there is one butterfly for one flower, there is one flower left.

=> y = x + 1

Also, if there are two butterflies on each flower, there is one flower left.

=> y = 2(x - 1)

Thus,

x + 1 = 2x - 2

x - 2x = -2 -1

-x = -3

=> x = 3

The number of butterflies = x = 3.

The number of flowers = y = x + 1 = 3 + 1 = 4.
