If the difference between discount of 50% and two successive discounts of 30% on a certain bill is Rs. 6, then what is the amount (in Rs.) of the bill?

Solution:

Let, amount of the bill = Rs. x

A can work twice as fast as B. A and C together can work thrice as fast as B. If A, B and C complete a job in 30 days working together, in how many days can each of them complete the work?

Solution:

A, B and C complete a job in 30 days working together,

⇒ 1/A + 1/B + 1/C = 1/30

A can work twice as fast as B,

⇒ 1/B = 1/2A

A and C together can work thrice as fast as B,

⇒ 1/B = 1/3(1/A + 1/C)

Solving,

⇒ 3/B = 1/A + 1/C

⇒ 3/B = 1/30 – 1/B

⇒ 1/B = 120

Then,

⇒ 1/A = 1/60

⇒ 1/C = 1/120

∴ A, B and C can complete work in 60, 120 and 120 days respectively.
