JEE Main- Top 30 Most Repeated Questions & Topics

Liner Differential equation is by far the most important topic with 102 questions more than any other topic ever repeated! The second is Area bound by two curves with 79 questions. The important thing to note is that the most important topic is clearly visible here with a huge marginal gap therefore you must lay a lot of importance on strategizing which topics to master! As an extra piece of information, Sum of n terms of an AP and Quadratic Equation come in the list after the Multiplication of two matrices but couldn’t make it to the top 10 most repeated topics in maths for JEE Mains. However, they can’t be ignored either.

Let’s go through the questions from each of the top 10 most repeated topics in Maths for JEE mains:

1. Linear Differential Equation

If x=f(y) is the solution of the differential equation

(1+y2)+(x−2etan−1⁡y)dydx=0,y∈(−π2,π2)

with f(0)=1, then f(13) is equal to:

Option 1: eπ/4, Option 2: eπ/12, Option 3: eπ/3, Option 4: eπ/6

{Solution:}
dxdy+x1+y2=2etan−1⁡y1+y2 I.F. =etan−1⁡yxetan−1⁡y=∫2e2tan−1⁡y1+y2dy Puttan −1y=t,dy1+y2=dtxetan−1⁡y=∫2e2tdt=e2tan−1⁡y+cx=etan−1⁡y+ce−tan−1⁡y Since y=0,x=1⇒1=1+c⇒c=0 For y=13,x=eπ/6

2. Area Bounded by Two Curves

If the area of the larger portion bounded between the curves x²+y²=25 and y=|x−1| is 14(bπ+c),b,c∈N, then b+c is equal to ........

{Solution:}
A=25π−∫−3425−x2dx+12(4⋅4)+12(3⋅3)A=25π+252−[x225−x2+252sin−1⁡(x5)]−34A=75π4+12=14(75π+2)

Thus, b=75,c=2⇒b+c=77.

% ---------------------------
3. Dispersion (Variance and Standard Deviation)

Mean and Variance of1,3,a,7,b are 5 and 10 respectively. Find the variance of 2,5,a+3,11,b+5.

{Solution:}5=1+3+a+7+b5⇒a+b=141+9+a2+49+b25−25=10⇒a2+b2=116.$

So a=10,b=4. New data: 2,5,13,11,9.

VVar=4+25+169+121+815−64=80.2−64=16.2≈16.

Hence, option (4).

4. General Term of Binomial Expansion

If coefficients of x4,x5,x6 in (1+x)n are in A.P., then maxn is?

2(n5)=(n4)+(n6).

Solving:
2=5n−4+n−56⇒n2−21n+98=0,
n=14 or 7,nmax=14.

Hence, option (1).

% ---------------------------
5. Cramer’s law

Coefficient of x2/3 and x−2/5 in (x2/3+12x−2/5)9.

Tr+1=(9r)(x2/3)9−r(x−2/52)r.

For x2/3 exponent:
23(9−r)−25r=23⇒r=55.

Coefficient: (95)(12)5.

For x−2/5 exponent:
23(9−r)−25r=−25⇒r=6

Coefficient: (96)(12)6

Sum =214.

Hence, option (1).

% ---------------------------
6. Vector (or Cross) Product of Two Vectors

Given a→=i^+2j^−3k^,b→=2i^+j^−k^. Condition:a→×r→=a→×b→,a→⋅r→=0.

After solving:
r→=32i^+12k^,|r→|=94+14=10/2≠10.

So Statement (I) false.
Statement (II): cos⁡2A+cos⁡2B+cos⁡2C≥−32 is true.

Hence, option (2).

7. Maxima and Minima of a Function

Roots of 2x2+(cos⁡θ)x−1=0 are α,β. Required: α4+β4.

α4+β4=(α2+β2)2−2(αβ)2.α+β=−cos⁡θ2,αβ=−12.

So expression =(cos2⁡θ4+1)2−12.Max=1716,min=12.

16(M+m)=25.

Hence, option (2).

% ---------------------------
8. Shortest Distance between Two Lines

Between parabola y2=8x and circle x2+y2+12y+35=0.

CentreC=(0,−6), radius =1. Normal meets circle at P(2,−4).

CP−r=(2−0)2+(−4+6)2−1=8−1=22−1.

Hence, option (4).

9. Application Of Inequality In Definite Integration

∫0π/4cos2⁡xsin2⁡x(cos3⁡x+sin3⁡x)2dx

Divide numerator/denominator by cos⁡x:

=∫0π/4tan2⁡xsec2⁡x(1+tan3⁡x)2dx

Lett=1+tan3⁡x, then dt=3tan2⁡xsec2⁡xdx

=13∫12dtt2=16

Hence, option (3).

10. Multiplication of two matrices

A=[1+i1−i0].

A2=[i1+i1−i−i],A4=I.

So A4p+1=A.Valid n=1,5,9,…,97. Total 25 values.

Answer: 25.
