2. The cost of paper production for 1 week is ₹1250. What is the cost of production for 1 year?

• A. ₹30,000; ₹1,00,000
• B. ₹18,000; ₹65,000
• C. ₹2,16,000; ₹65,000
• D. ₹2,16,000; ₹60,000

Answer 1

The correct option is C ₹2,16,000; ₹65,000

1. The dealer buys 20 dozen bicycles. We know that 1 dozen comprises 12 parts.
So, the total number of bicycles = 12 × 20 = 240

Cost of one bicycle = ₹900
=> Cost of 240 bicycles = 240 × 900 = ₹2,16,000

Hence, the cost of 20 dozen bicycles is ₹2,16,000.

2. The cost of paper production is given as ₹1250 per week. To find the cost of production for 1 year,

We know that a year has 52 weeks.

So, the cost of production for 1 year = 1250 × 52 = ₹65,000

Hence, the cost of paper production for 1 year is ₹65,000.
