At a flower show which 1250 attended, outsiders were charged $1, villagers $ 0.5 and school children $ 0.05. The total receipt from the flower show was $695. There were 3 times as many villagers as outsiders. How many outsiders came to the show?
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.

Simultaneous equation
Two persons A and B are 27 km apart, setting out at the same time, are together in 9 hours if they walk in the same direction, but in 3 hours if they walk in opposite directions. Find their rate of walking.
Simultaneous equation
A, B and C travel from the same place at the rates of 5, 6 and 8 km/hr respectively. If B starts 2 hours after A, how long after B must C start in order that they may overtake A at the same instant?

Simultaneous Equation
A train running from A to B meets with an accident 75 km from A, after which it travels with 3/5th of its original velocity and arrives 3 hours late at B. If the accident had occurred 75 km further on, it would have been only 2 hours late. Find the distance from A to B and the original velocity of the train.
Simultaneous Equations
If 2 rabbits and 4 dogs cost $ 1750, three dogs and 2 cats cost $ 1725 and one cat and 3 rabbits cost $ 675. Find the price of each.
Let cost of 1 rabbit = R, cost of 1 dog = D, cost of 1 cat = C
Let cost of 1 rabbit = R, cost of 1 dog = D, cost of 1 cat = C
Simultaneous Equations
Two numbers are formed by the same two digits, and if the smaller number is divided by the greater the quotient is 4/7, and if the smaller is subtracted from the greater the remainder is 27. Find the number.
simultaneous equation
