Question

if 10% of M is twice the 20% of n then M:n is equal to

Answer 1

$\textbf{\huge{ANSWER:}}$

Given:

10% of M = 20% of N

Solving the given equation:

=》 $\frac{10}{100}M = \frac{20}{100}N$

=》 $\frac{M}{10} = \frac{N}{5}$

=》 5M = 10N

=》 $M = \frac{10N}{5}$

=》 $\textbf{M = 2N}$
___
=》 $N = \frac{5M}{10}$

=》 $\textbf{N = \frac{M}{2}}$
___
=》 $\frac{M}{N} = \frac{2N}{M}÷2$

=》 $\frac{M}{N} = \frac{4N}{M}$

=》 $M^{2} = 4N^{2}$

=》 $\frac{M^{2}}{N^{2}} = 4$

Rooting on both the sides:

=》 $\frac{M}{N} = \sqrt4$

=》 $\frac{M}{N} = 2$

=》 M : N = 2 : 1
