Question: The manufactures of ‘Bajaj’ scooter give choice to their customers to have either a double seated scooter or a single seated scooter. On analysis of the booked orders for those scooters, they find that 75% of their customers are men and 25% women. 80% of the men customers prefer double seated scooters and rest one seated. 90% of their women customers prefer one seated scooters and rest two seated scooters. In what proportion, the manufacturers should manufacture these two scooters?

Solution:

Men customers preferring tow seater        = .75 x .8 = .600

Women customers preferring two-seater = .25 x .1 = .025

Total = .625

Men customers preferring one-seater        = .75 x .2 = .150

Women customers preferring one-seater = .25 x .9 = .225

Total                                                              = .375

Ratio .675: .375

or

5 : 3
