In a shipment of airplane parts 3% are known to be defective . if 15 parts are found to be defective how many parts are in the shipment

500

Step-by-step explanation:

Let Y represent the number of parts in the shipment.

Number of Defective parts found in the shipment= 15

Percentage (%) of known Defective parts in the shipment = 3%

3% = 3/100

Therefore,

(3 ÷ 100) × Y = 15

We have

3Y ÷ 100 = 15

Cross multiply

3Y = 15 × 100

3Y = 1500

Y = 1500 ÷ 3

Y = 500

Therefore, the number of parts in the shipment is 500.
