Question

Harry Sells blue and pink fidget spinners the price of the blue spinners is rs 140 per piece and the price of pink spinners are rs 120 per piece. if a total of 11880 was earned by selling 90 spinners, then find the number of each type of spinner sold.

Answer 1

Answer:Blue spinners sold = 54

Pink spinner sold = 36

Step-by-step explanation:

Let Number of blue spinner sold be x

Let Number of pink spinner sold be y

Therefore we can form 2 equations:

=> 140x+120y=11880

=> or 14x + 12y = 1188 _______1

And

=> x + y = 90

=> or x = 90 - y

Now, substituting the value of x in eq. 1

We get

=> 14(90-y) + 12y = 1188

=> or 1260 - 14y +12y = 1188

=> or -2y = -1260 + 1188

=> or -2y = -72

=> or y = 72/2

=> or y = 36

Therefore x = 90 - y

x = 90 -36

x = 54

Blue spinners sold (x) = 54

Pink spinner sold (y) = 36

Hope you understand the Answer. And best of luck for your bright future.
