XAT 2024 Formula Topics

XAT Formulas

Basic Mathematical Formulas

• (a + b)² = (a² + b² + 2ab)
• (a – b)² = (a² + b² – 2ab)
• (a + b)(a – b) = (a² – b²)
• (a + b)² = (a² + b² + 2ab)
• (a³ – b³) = (a – b)(a² + ab + b²)
• (a + b + c)² = a² + b² + c² + 2(ab + bc + ca)
• (a³ + b³) = (a + b)(a² – ab + b²)
• When a + b + c = 0, then a³ + b³ + c³ = 3abc
• (a³ + b³ + c³ – 3abc) = (a + b + c)(a² + b² + c² – ab – bc – ac)
• (a + b)n = an + (nC1)an-1b + (nC2)an-2b² + … + (nCn-1)abn-1 + bn

Number System

• (1² + 2² + 3² + ….. + n²) = n ( n + 1 ) (2n + 1) / 6
• 1 + 2 + 3 + 4 + 5 + … + n = n(n + 1)/2
• (1³ + 2³ + 3³ + ….. + n³) = (n(n + 1)/ 2)²
• Sum of first n odd numbers = n²
• Sum of first n even numbers = n (n + 1)

LCM and HCF

• LCM × HCF = Product of the Numbers
• LCM of Co-prime Numbers = Product Of The Numbers

Profit, Loss, and Discount

• Profit % = Profit/(C P)×100
• Profit/Gain = (S.P.) – (C.P.)
• C P = 100/(100+gain %)×S P
• S P = (100+gain % )/100 ×C P
• Loss % = Loss/(C.P.)×100
• Loss = (C.P.) – (S.P.)
• C P = 100/(100-loss %)×S P
• S P = (100-loss %)/100×C P

Percentages

• Find what percentage of X is Y: Y/X x 100
• Increase N by S% = N(1+S/100)
• Decrease N by S% = N(1 - S/100)

Speed, Time, and Distance

• Speed= Distance/ Time
• Distance= Speed x Time
• Time= Distance/ Time

Time and Work Formulas (Basic Formulas)

• If X can do a piece of work in ‘n’ days, then X’s 1 day’s work = 1/n
• If X’s 1 day’s work = is 1/n, then X can finish the work in n days.

Average Formula

• Average= Sum of observations/ Number of observations

Simple and Compound Interest Formula

• Simple Interest: P x i x n (P= Principle, i= interest rate and n= term of the loan)
• Compound Interest:
• Compound Interest = [P(1+i)n] - P
• Compound Interest = P[(1+i)n-1]
