NCERT Maths Solution Class 8 Exercise 2.6
Problems in Exercise 2.6 require the knowledge of reducing non-linear equations (reducible) to linear equations.
Some equations may not be linear to begin with, but they can be brought to linear form by multiplying both sides of the equation by a suitable expression.[ NCERT MATHS SOLUTION CLASS 8 EXERCISE 2.6 ]
Cross Multiplication :
If an equation is in the form we multiply both LHS and RHS with b and d but omit the step and write the result in next step as .
Equations Reducible to the Linear Form
Solve the following equations.
6). The ages of Hari and Harry are in the ratio 5:7. Four years from now the ratio of
their ages will be 3:4. Find their present ages.
Let, the age of Hari be 5x years,
So, the age of Harry be 7x years,
Four years from now,
The age of Hari will be (5x + 4) years,
and the age of Harry will be (7x + 4) years,
7). The denominator of a rational number is greater than its numerator by 8. If the
numerator is increased by 17 and the denominator is decreased by 1, the number
obtained is . Find the rational number.
Let, the numerator of the rational number be x,
So, the denominator of the rational number be x + 8,
Therefore, the numerator of the rational number = x = 13,
and the denominator of the rational number = x + 8 = 21,
Hence, the rational number =
