SSC CGL Math’s Tricks with Solution 2017

. If the value of something is increased by x % and again increased by y % then resulting effect in percent Total change = {x+ y+ x*y/100} Example : The Salary of a worker is first increased by 10% and thereafter increased by 5%. What is the overall change in percent? Solution: overall change = + 10 + 5 + (+10)(+5)/100 = +15.5 % (increased) use (+) sign for increment and (-) sign for decrement.

2.If the value of something is increased by x % then decreased by y % then resulting effect in percent Total change = {+x- y+ (x*(-y)/100)} Example : The Salary of a worker is first increased by 10% and thereafter decreased by 5%. What is the overall change in percent? Solution: overall change = + 10 – 5 +(10)(-5)/100 = +4.5 % (increased) use (+) sign for increment and (-) sign for decrement.

3. If the value of something is decreased by x % and again decreased by y % then resulting effect in percent Total change = {-x – y + (-x)*(-y)/100} Example : The Salary of a worker is first decreased by 10% and thereafter decreased by 5%. What is the overall change in percent? Solution: overall change = – 10 – 5+ (-10)(-5)/100 = -14.5 % (decreased) use (+) sign for increment and (-) sign for decrement.

Now, this is just the formula but its application is endless in the question of percentage, for the questions like- 1. If both the lengths (%) and breadth (%) of a rectangle are changed find the change in area (%)? 2. If the speed and time of a vehicle are changed, find the change in distance? Similarly in all those questions where two quantities are multiplied to produce third one rate * time = cost efficiency * time = work average * no. of elements = total value rate * quantity = price (expenditure)
