Question

My question is: there is a Garland with white, red and yellow flowers is 54 in numbers. Red flowers are one less than twice of yellow flower, white flower is 1 more than twice of red flowers. If then yellow flower no. is 20,then find the number of white flower?​

Answer 1

Answer:

Step-by-step explanation:

CASE -1

Let the numbers of red flower be x

x = 20 × 2 - 1

  = 40 - 1 = 39

Thus, no. of red flower is 39

CASE-2

Let the number of white flower be y

y = 2 × 39 + 1

  = 78 + 1 = 79

THIS ANSWER IS NOT APPROPRIATE AS TOTAL NO. OF FLOWER IS 54.

SO I AM WRITING THE A ANOTHER ANSWER FOR THIS QUESTION

Let the no. of white flower be x

So, no. of red flower is = 2x - 1

So, no of white flower is = 2(2x-1) + 1 = 4x -1

NOW,

 x + 2x -1 + 4x -1 = 54

⇒ 7x - 2 = 54

⇒ 7x = 54 + 2 = 56

⇒ x = 56/7 = 8

Thus , no. of yellow flower = 8

           no. of red flower = 16 - 1 = 15

           no. of white flower = 4 × 8 + 1 = 32 +1 = 33
