- Successive percentage change
- Two successive changes of a% and b% give a net change of a + b + ab/100 percent; a 10% rise then 10% fall gives a 1% net fall.
- Compound interest formula
- Amount A = P(1 + R/100)^T, where P is principal, R the annual rate and T the time in years; CI = A - P.
- HCF and LCM relation
- For two positive integers, HCF multiplied by LCM equals the product of the two numbers.
- Divisibility by 11
- A number is divisible by 11 if the difference between the sums of digits in alternating positions is 0 or a multiple of 11.
- Sphere volume
- The volume of a sphere of radius r is 4/3 pi r cubed; its surface area is 4 pi r squared.
- Speed conversion
- To convert kilometres per hour to metres per second, multiply by 5/18; to reverse, multiply by 18/5.
- Time and work formula
- If A alone takes x days and B alone y days, working together they finish the job in xy/(x + y) days.
- Profit percentage
- Profit percent equals (selling price - cost price) divided by cost price, multiplied by 100; loss percent uses the same base.
- EJOTY trick

- Circular arrangement count
- For n people seated in a circle facing the centre, clockwise is the person's left; each person has two neighbours, giving n-1 relative positions.
- Direction displacement
- After successive right-angle turns, net displacement is found by Pythagoras: 3 km east then 4 km north gives a 5 km straight-line distance.
- Number series check
- Test differences first, then second differences, then squares, cubes and primes; alternating series often combine two separate patterns.
- स्वर और व्यंजन
- हिंदी में स्वर 11 माने जाते हैं और व्यंजन 33; क्ष, त्र, ज्ञ, श्र संयुक्त व्यंजन हैं।
- तत्पुरुष समास
