• D. ₹ 159.60

Answer 1

The correct option is B

₹ 157.80

The total length of the pole is the sum of the portion that is painted in red, white, black and the portion left unpainted.
The total length of the pole is = 0.35 + 1.27 + 3.27 + 5.63

$0.35$
$+1.27$
$+3.27$
$+5.63$
$\overline{}$
$10.52$
$\overline{}$

The total length of the pole is 10.52 m

If we need to paint the entire pole including the region which is left unpainted Total cost = 10.52 $\times$ 15 = ₹ 157.80
