Question

In the following question given below, use the following notations :

A " B means "add B to A"

A ' B means "subtract B from A"

A @ B means "divide A by B"

A ★ B means "multiply by A by B"

The total airfare is calculated by adding $15\%$ basic fare as fuel surcharge, $2\%$ of basic fare as IATA charges and $Rs.200$ as airport tax to the basic fare. If the basic fare of a section is $B$, which of the following will represent the total fare?

• A. B '(B $★$ 15) @ 100 " (B $★$ 2) @ 100 "200
• B. B "(B $★$ 15) @ 100 " (B $★$ 2) @ 100 "100
• C. B "(B $★$ 15) @ 100 " (B $★$ 2) @ 100 "200
• D. B "(B $★$ 15) @ 200 " (B $★$ 5) @ 200 "100

Answer 1

The correct option is C B "(B $★$ 15) @ 100 " (B $★$ 2) @ 100 "200

According to the question after taking all the fares into account we get:

Total fare$=B+\frac{15}{100}\times B+\frac{2}{100}\times B+200$
Exchange the sign according to the question then
B" (15 @ 100 $★$ B) " (2 @ 100 $★$ B) " 200
Hence option C is answer.
