If a candidate wants to solve the SSC CGL Exam within time then they must learn the SSC CGL Maths Short Tricks to attempt the questions and solve them quickly. It is possible that one can solve the questions without using short tricks but as per the experts, using the short tricks is very important it not only saves time but also increases the accuracy of the exam. Below we have provided the SSC CGL Maths Short Tricks candidates must follow:
1. If a number is first decreased by a% and then by b%, then the net change in percent is (–ve sign for decrease):
2. The average of ‘n’ consecutive natural numbers starting from 1 i.e. Average of 1,2,3, …..n:
3. Mean Proportion – Let x be the mean proportion between a and b, then a:x::x:b
So, the mean proportion of a and b = √(a × b)
4. If cost price of ‘x’ articles is equal to selling price of ‘y’ articles, then Selling Price = x, Cost Price = y
5. When two successive discounts are given, the overall discount is
6. If a certain sum P amounts to Rs. A1 in t1 years at rate of R% and the same sum amounts to Rs. A2 in t2 years at same rate of interest R%. Then,
7. If A and B can do a work in ‘x’ days, B and C can do the same work in ‘y’ days, C and A can do the same work in ‘z’ days. Then total time taken, when A, B and C work together
8. Time taken by 1st man to reach B after meeting 2nd man at C is ‘t1 ’ and time taken by 2nd man to reach A after meeting 1st man at C is ‘t2 ’ then:
9. The largest number which when divide the numbers a, b and c give remainders as p, q, r respectively is given by:
H.C.F. of (a – p), s(b – q) and (c – r)
10. The recurring decimal numbers of type 0.x or 0.xyz may be converted to rational form as
SSC CGL Maths Formulas is very important to solve the questions very quickly. Candidates are advised that they should be prepared with all the formulas learned and practiced already to avoid any mistakes during the exam. Candidates must make a small note and write down all the formulas in that note. Candidates must keep revising the formulas daily.
