Q.

The true length of the line is 30 cm and isometric view is drawn. How much length is reduced?

A. 24.45 cm
B. 25.98 cm
C. 4.01 cm
D. 5.55 cm
Answer» D. 5.55 cm
Explanation: the ratio of isometric length to true length is 0.815 so here it is given true length of 30 cm. 0.815 = isometric length / 30 cm => isometric length = 30 cm x 0.815 = 24.45 cm. 30 cm – 24.45 cm =5.55 cm.
