The inflation in the
economy is @ 9% per annum. A company decides to revise the salary of all its
employees by 5%. By how much should the consumption by individuals come down so
as to beat the inflation?
This blog makes available plenty of questions for practice, for the Mathematics competitive exams. We also try to bring to students interesting ways of approaching the questions. If you need any assistance in questions from IPM, MTSE, SCHOLARSHIP, OLYMPIAD, CBSE , ICSE or Board test papers, you may write to us.

percentage
A farmer stores 10000
kg of potatoes in an underground cellar. At the prevailing buying rates in the
whole sale market he is unable to make any profit. He is advised that the
market price of potatoes will climb @ 3% per month, whereas the loss in weight
of potatoes due to evaporation of water was @1% per month.
After how many months
should he sell his stock of potatoes so as to make a profit of 10%.

point (3, 4) and is Parallel to AB?
8-equation of perpendicular to given line
Two points A and B have the following coordinated (2, 2) and
(10, 8) respectively.
Find the equation of straight line which passes through
point (3, 4) and in perpendicular to AB?
7-dividing a line segment to a given ratio
Two points A and B have the following coordinated (2,2) and
(10,8) respectively.
Find the coordinates that divide the line segment in the
ratio of 2:3?
6-midpoint of a line segment

16-time and work
A can do a piece of work in 9 days and B
can do a piece of work in 12 days respectively. If they work only on alternate
days, then how many days will it take for the work to get completed?
15-chain rule / time and work
If 10 workers can dig a trench 23/4 feet long in one day, then how many workers will be required to dig a trench 23 feet long in 3 days time?
14-chain rule / time and work
For a certain job, 60 days are required
for a group of men. If 8 more are added to the group, then it would take 10
less days to complete the job. How many men were there initially?
13-chain rule / time and work
8 men or 12 boys can do a piece of work
in 50 days. In how many days will 11 boys and 6 men do the job?
12-chain rule / time and work
6 men or 12 boys can do a piece of work
in 40 days. In how many days will 16 boys and 24 men do the job?
11-time and work / chain rule
For a certain job, 40 days are required
for a group of men. If 12 out of the group never turned up for the job, then it
took the remaining men 64 days to get the job completed. How many men were
there initially?
