Then, 5% of x = 50/100
x ‹=› (50/100×100/5)
= 10
Cost of tax free items = Rs.[100 - (10 + 0.50)]
= Rs. 89.50

Two fill pipes A and B can fill a cistern in 12 and 16 minutes respectively. Both fill pipes are opened together, but 4 minutes before the cistern is full, one pipe A is closed. How much time will the cistern take to fill ? | [
"5 min.",
"9 1⁄7min.",
"3 1⁄3min.",
"3 min."
] | B | Let cistern will be full in x min. Then,
part filled by B in x min + part filled by A in (x – 4)min = 1
⇒ x/16+x−4/12=1
⇒ x = 64⁄7 = 91⁄7 hours.

It takes Avery 5 hours to build a brick wall while Tom can do it in 4 hours. If the two start working together and after an hour Avery leaves, how much time will it take Tom to complete the wall on his own? | [
"55 minutes",
"2 hours and 12 minutes.",
"1 hour and 20 minutes.",
"2 hours and 20 minutes"
] | B | Avery's efficiency is 100/5 = 20%
Tom's = 100/4= 25%
they worked together for 1 hour and finished 45% of the job
remaining = 55 %
Tom will complete 25% in 60 minutes , 50% in 120 minutes and ,
5% in 60*5/25 minutes = 12 minutes
time taken by Tom to finish the remaining on his own = 120+12 = 132 minutes

Of the science books in a certain supply room, 50 are on botany, 55 are on zoology, 90 are on physics, 50 are on geology, and 110 are on chemistry. If science books are removed randomly from the supply room, how many must be removed to ensure that 80 of the books removed are on the same area science? | [
"166",
"314",
"159",
"81"
] | B | The worst case scenario is to remove all the books on botany, zoology, and geology.
Also we can remove 79 books each from physics and chemistry.
The total is 50 + 55 + 50 + 79 + 79 = 313.
The next book removed must either be physics or chemistry, ensuring 80 books in that subject.
