10th Grade Math Problems

Back to Top
Few problems based on 10th Grade math are given below:

Solved Examples

Question 1: Aline is 10 years older than Alice. In 12 years, the sum of their ages will be 40. How old are Aline and Alice now ?
Solution:
 
Let Alica's age be represented with x and Aline's age represented with x + 10.

In 12 years:

Add 12 to both ages

Alica's age = x + 12 and Aline's age = (x + 10) + 12 = x + 22

The sum of their ages in 12 years will be 40, so the equation is as follows:

=> x + 12 + x + 22 = 40

=> 2x + 34 = 40

=> 2x = 40 - 34 = 6

or x = $\frac{6}{2}$ = 3

So Alica is 3, and Aline is 13 (i.e. 3 + 10).
 

Question 2: Solve the system of linear equation 5m + 2n = 14 and 2m - n = 2.
Solution:
 
Given: 5m + 2n = 14   ..........(1)

2m - n = 2 ..............(2)

Use the substitution method to solve the given system

Step 1
: Solve the second equation for n

=> n = 2m - 2

Substitute this solution for n in equation (1)

=> 5m + 2(2m - 2) = 14  

Solve for m

5m + 4m - 4 = 14

9m = 18

or m = $\frac{18}{9}$ = 2

Step 2:
Again substitute this solution for m in equation (2)

2 * 2 - n = 2

4 - n = 2

n = 2

The solution for the given system is (2, 2).

Few problems based on geometry are given below:

Solved Examples

Question 1: Find the area of segment of a circle whose angle is 130$^o$ and its radius is 10 cm.
Solution:
 
Given that the angle is 130$^o$ and its radius is 10 cm.

The formula to find the area of segment of a circle is $\frac{r^2}{2}$ $((\frac{\pi}{180^o})$ $\theta$ - sin $\theta)$

Substitute the given values in the formula

$\frac{r^2}{2}$ $((\frac{\pi}{180^o})$ $\theta$ - sin $\theta)$

$\frac{10^2}{2}$ $((\frac{\pi}{180^o})$ $\times$ 130$^o$ - sin 130$^o$)

= 75.1 cm$^2$.
 

Question 2: Find the missing angles x , y and z in the following figure.
10th Grade Geometry Problem
Solution:
 
As the pair 58$^o$, y and x, z are alternate interior angles, they are equal in measure.

So, y = 58$^o$

58$^o$ + x = 180$^o$  (Linear pair)

x = 180$^o$ - 58$^o$

= 122$^o$

Since x and z are alternate interior angles, they are equal in measure

So, z = 122$^o$.
