Calculation of Percentage: Let’s solve the problem “What is 30% of 80?” Now, we can write: x = 30/100 * 80. The answer is 24. Let’s start with the number 120. First, we create a quick chart as follows: 120 = 100% 12 = 10% 1.2 = 1% 60 = 50% 6 = 5% Now, we can solve the problems using this base numbers. Example 6% of 120 = 5% + 1% = 6 + 1.2 =7.2 One other type of calcula...

Simplifications Problems: We must remember all basic concepts and tricks used to solve these numerical on simplification. 1) Numbers 2) H.C.F. and L.C.M. 3) Decimal fractions 4) Square and cube roots 5) Surds and indices Important points to Remember: 1) This chapter is very important because numerical on simplification is based on concepts related to decimal to fraction, square...

Boat and Stream Questions: Downstream: In water, the direction of a boat along with the stream is called Downstream. Upstream: The direction of a boat against the stream is called Upstream. Formulas: Speed Downstream = ( u + v ) km/hr Speed Upstream = ( u – v ) km/hr If the speed downstream is x km/hr and the speed upstream is y km/hr then, Speed in Still Water = 1 / 2 ( x +...
