Most Challenging Class 10th Math Problems
Class 10 mathematics is an important milestone in a student's education, especially in the Indian system. The syllabus introduces challenging topics like algebra, geometry, trigonometry, and statistics to build problem-solving skills.
Each chapter presents unique challenges and concepts that require a deep understanding and analytical thinking.
Real Numbers
One of the toughest questions in this chapter involves proving irrationality or finding HCF and LCM using prime factorization.
Example Question: Prove that 22 is irrational.
Solution:
Assume 22 is rational, which means it can be expressed as pqqp, where pp and qq are coprime integers. Then:
Root 2=qp⟹2=q2p2⟹p2=2q2
This implies that p2 is even, hence p must be even (since the square of an odd number is odd). Let p=2kp=2k:
(2k)2=2q2 ⟹ 4k2=2q2 ⟹ q2=2k2
Thus, q is also even, contradicting our assumption that pp and qq are coprime. Therefore, 22 is irrational.
Polynomials
Example Question: Find the zeros of the polynomial f(x)=x2−5x+6.
Solution:
To find the zeros, we set f(x)=0f(x)=0:
x2−5x+6=0
Factoring gives:
(x−2)(x−3)=0
Thus, the zeros are x=2 and x=3.
Pair of Linear Equations
Example Question: Solve the following equations:
-
3x+4y=103x+4y=10
-
5x−3y=−15x−3y=−1
Solution:
Using the elimination method:Multiply the first equation by 33:
9x+12y=30
Multiply the second equation by 44:
20x−12y=−4
Adding these equations:
29x=26 ⟹ x=2629
Substituting x back into one of the original equations to find y.
Quadratic Equations
Example Question: Solve for roots using the quadratic formula for x2+x−6=0.
Solution:Using the quadratic formula:
x=−b±b2−4ac2a
Here, a=1,b=1,c=−6a=1,b=1,c=−6:
Calculating:
b2−4ac=1+24=25
Thus,
x=−1±52x=2−1±5
This gives us roots x=2 and x=−3.
Trigonometry
Trigonometry poses some of the hardest questions for Class 10 students.
Example Question: Find the height of a tower if the angle of elevation from a point on the ground is 30∘30∘, and the distance from that point to the base of the tower is 50m.50m.
Solution:
Using tangent function:
Let height be h:
tan(30∘)=h50 ⟹ h=50tan(30∘)
Since tan(30∘)=13tan(30∘)=31:Thus,
h=503≈28.87mh=350≈28.87m

Hardest Questions of Maths Class 10 Trigonometry
Trigonometry remains one of the most challenging areas in Class 10 mathematics.
Example Question: Prove that:
1+tan2(A)=sec2(A)
Solution:Using Pythagorean identities:
Starting from left side,
1+tan2(A)=sec2(A)
This follows from
tan(A)=sin(A)cos(A)and sec(A)=1cos(A).Therefore proved
