How to Solve SI Questions in Less Time?

You must already be aware of the importance of time in the RRB Clerk Exam. Time is the key. You need to know the tips and tricks to solve SI questions faster. You should learn to break down the formula into smaller chunks. You can also practice mental calculation of percentages. Memorising common interest patterns will turn out to be a boon for you, like 10% for 1 year = 10% of principal. Use short tricks when possible, especially for reverse problems. Even solving 10-15 targeted questions a day can increase your speed and confidence drastically.

How to Practice More Effectively?

The more you practice, the more perfect you’ll become. Try starting your day with a 10-minute SI practice drill, keep a notebook of formulas and shortcut tricks, attempt quizzes or topic-wise mocks on platforms like PracticeMock, and analyse your weak points and revisit the concept when needed. Remember, consistency is more powerful than cramming. If you practice 10 questions a day, that will give you better results than practising 100 questions once a week.
