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