Direction: Answer the following questions from data mentioned in case...
Given
Number of customers with bank A = 300,000
Number of customers with bank C = 300,000 × 1.5 = 450,000
Number of customers with bank B = 250,000 (i.e. 300,000 – 50,000)
Bank A and C common registrations = 20,000
Formula used: Ratio of A to B = A : B
Number of registered customers for only Bank A = Total number of registered customers for bank A – Common registered customers with B – Common registered customers with Bank C – All common registered customers
Number of registered customers with bank A = 0.25 × 300,000 = 75,000
Number of registered customers with bank C = 0.35 × 450,000 = 157,500
Number of registered customers with Bank B = 0.20 × 250,000 = 50,000
Number of common registrations between bank B an C but not with A = 10% of customers Bank B’s registered customers = 5,000 (i.e. 10% of 50,000)
Ratio of common registrations between bank B with bank C to Bank A with bank B = 1 : 3
⇒ Common registration between Bank A and Bank B but not C = 3 × 5000 = 15000
⇒ Bank A, B and C has 2% of common registration from total customers = 0.02 × 1,000,000 = 20,000
⇒ Values in Venn diagram includes only A, only B and only C.
Number of registered customers with only Bank A = 75,000 – 20,000 – 15,000 – 20,000 = 20,000
Required Ratio = Registered customers with only bank A : Registered customers with Bank B = 20,000 : 50,000 = 2 : 5
Hence, the correct option is (B).
