In this case it will be (4 + 1)*(1 + 1) = 5 * 2 = 10 (the power of 2 is 4 and the power of 3 is 1) Therefore, there will 10 factors including 1 and 48. Sum of n natural numbers -> The sum of first n natural numbers = n (n+1)/2 -> The sum of squares of first n natural numbers is n (n+1)(2n+1)/6 -> The sum of first n even numbers= n (n+1) -> The sum of first n odd numbers= n^2 Finding Squares of numbers To find the squares of numbers near numbers of which squares are known To find 41^2 , Add 40+41 to 1600 =1681 To find 59^2 , Subtract 60^2-(60+59) =3481 Finding number of Positive Roots If an equation (i:e f(x)=0 ) contains all positive co-efficient of any powers of x , it has no positive roots then.
Eg: x^4+3x^2+2x+6=0 has no positive roots . Short cut methods in quantitative aptitude-aptitude tricks.

Solution: Let the present age of son = x years the present age of father = 5x years 3 years ago sons age = x-3 Fathers age = 5x-3 7(x-3) = 5x-3 7x-21=5x-3 2x=18 x=9 So, Present age of son is 9 years and father is 5*9=45. Shortcut Sons Age = T1(x-1)/x-y= 3*(7-1)/(7-5) = 9 Example 2 A sum of money doubles itself in 10years at S.I . Solution: Let the sum be x After 10 years it becomes 2x Interest= Rs.2x- Rs.x =Rs.x Rate = 100*l/P*T =100*x/x*10 = 10% Example.
