Answer 1

Answer:

$\huge\red{\underline{\mathbb{Explanation:-}}}$

Cost of 25 m of cloth = ₹ 1012.50

(i) Cost of 1 m of cloth = ₹ (1012.50/25)

∴ Cost of 20 m of cloth = ₹ (1012.50/25) × 20

= ₹ 810

(ii) Cloth purchased by ₹ 1012.5 = 25 m

Cloth purchased by ₹ 1 = 25/1012.5

∴ Cloth purchased by ₹ 1620 = (25/1012.5) × 1620 = 40 metres
