CAT 2022 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

Formulas for LCM and HCF

Important Formulas for 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= 1/n, then X can finish the work in n days.

CAT Quant Formulas PDF Number Systems

• 1 + 2 + 3 + 4 + 5 + … + n = n(n + 1)/2
• (1² + 2² + 3² + ….. + n²) = n ( n + 1 ) (2n + 1) / 6
• (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)

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

Profit, Loss, and Discount

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