Sum

Three friends had dinner at a restaurant 2/3 When the bill was received, Alpana paid as much as Beena paid and Beena paid 1/2 as much as Catherin paid. What fraction of the bill did Beena pay?

#### Solution

Let ‘T’ be the total bill amount at the restaurant and ‘a’, ‘b’, and ‘c’ be the share of Alpana, Beena, and Catherin respectively.

Given, that Alpana paid rd 2^"rd"/3 as much as Beena paid

∴ a = 2/3b               ................(i)

Also, Beena paid 1/2 as much as Catherin paid.

∴ b = 1/2 c i.e. c = 2b        ..................(ii)

∴ Three friends paid the total bill amount.

∴ a + b + c = T               ..................(iii)

Using (i) and (ii) in (iii), we get

2/3b + b + 2b = T

∴ b(2/3 + 1 + 2) = "T"

∴ b((2 + 3 + 6)/3) = T

∴ (11"b")/3 = T

∴ b = 3/11T

Thus, Beena paid (3/11)^"th" fraction of the total bill amount.
