UPTET Paper 1 Model Test 3

Concept:1 rupee = 100 paise. 25 paise = $\frac{1}{4}$ rupee, 50 paise = $\frac{1}{2}$ rupee. 1 lakh = 1,00,000 rupees.Explanation:Check each option step by step to find the incorrect one.Option A: 80 coins of 25 paise = $80 \times \frac{1}{4} = 20$ rupees. 160 coins of 50 paise = $160 \times \frac{1}{2} = 80$ rupees. Total = $20 + 80 = 100$ rupees. $\frac{1}{5}$ of a 500‑rupee note = $500 \div 5 = 100$ rupees. So this statement is correct.Option B: 200 notes of 500 rupees = $200 \times 500 = 1,00,000$ rupees = 1 lakh rupees. This is correct.Option C: 2000 notes of 200 rupees = $2000 \times 200 = 4,00,000$ rupees = 4 lakh rupees, not 40 lakh rupees. This statement is incorrect.Option D: 80 coins of 50 paise = $80 \times \frac{1}{2} = 40$ rupees. 160 coins of 25 paise = $160 \times \frac{1}{4} = 40$ rupees. Total = $40 + 40 = 80$ rupees. Rs. 80 is Rs. 20 less than Rs. 100. This statement is correct.Only option C is incorrect.Answer:C. Two thousand 200‑rupee notes are equivalent to Rs. 40 lakh
