Mazyrski [523]

Mumbi is approximately 845 kilometers away from Bangalore, and Mumbai is approximately 1160 km away from Delhi, then the ratio between these distances is

\dfrac{845}{1160}=\dfrac{169}{232}.

A. Bangalore to Mumbai: 116.5 cm;

Mumbai to Delhi: 174 cm

The ratio:

\dfrac{116.5}{174}=\dfrac{233}{348}\neq \dfrac{169}{232}

This option is false.

B. Bangalore to Mumbai: 42.25

Mumbai to Delhi: 58 cm

The ratio is

\dfrac{42.25}{58}=\dfrac{845}{1160}=\dfrac{169}{232}

This option is true.

C. Bangalore to Mumbai: 23.4 cm

Mumbai to Delhi: 29 cm

The ratio is

\dfrac{23.4}{29}=\dfrac{117}{145}\neq \dfrac{169}{232}

This option is false.

D. Bangalore to Mumbai: 16.9 cm

Mumbai to Delhi: 23.2 cm

The ratio is

\dfrac{16.9}{23.2}=\dfrac{169}{232}

This option is true.

E. Bangalore to Mumbai: 25.35 cm

Mumbai to Delhi: 34.8cm

The ratio is

\dfrac{25.35}{34.8}=\dfrac{507}{696}=\dfrac{169}{232}
