Answer 1

Answer:

Rs. 384

Brainly Solution:

20% of 320

⇒ $\sf \dfrac{20}{100}$ × 320

⇒ 2 × 32

⇒ 64

∴ Increase Amount = Rs. 320 + Rs. 64

                                = Rs. 384

Answer 2

New value =

400 + Percentage increase =

400 + (- 20% × 400) =

400 - 20% × 400 =

(1 - 20%) × 400 =

(100% - 20%) × 400 =

80% × 400 =

80 ÷ 100 × 400 =

80 × 400 ÷ 100 =

32,000 ÷ 100 =

320;
