Answer 1

Answer:

b part is the correct answer

Answer 2

Explanation:

wage for per hours = Rs. 1.80

total wages for 40 hrs = 40 × 1.80 = Rs. 72

material wasted = 8×$\frac{20}{100}$

= 1.6 kg

total weight of the raw material = 1.6 kg + 8 kg = 9.6 kg

cost of the raw material per kg = Rs. 22.5

Total cost of the raw material  = 22.5 × 9.6 = Rs. 216

then

Total cost price = 216 + 72 = Rs. 288

then

selling price = $288 \times \frac{33.33}{100}$

= Rs. 383.99  ≈ Rs. 384

hence , The selling price is Rs. 384
