If 3 kg of sugar costs Rs. 150, what is the cost of 5 kg of sugar?
Show answer
Answer: B. Rs. 250
First, find the cost of 1 kg of sugar. Cost of 1 kg = Rs. 150 / 3 kg = Rs. 50/kg. Then, calculate the cost of 5 kg. Cost of 5 kg = 5 kg * Rs. 50/kg = Rs. 250.
What percentage of 50 is 20?
Show answer
Answer: C. 40%
Let the percentage be 'p'. (p/100) * 50 = 20. p * 50 = 20 * 100. p * 50 = 2000. p = 2000 / 50 = 40. So, it is 40%.
What is 75% of 200?
Show answer
Answer: B. 150
75% of 200 = (75/100) * 200 = 75 * 2 = 150.
A shopkeeper buys a pen for Rs. 100 and sells it at a loss of 15%. What is the selling price?
Show answer
Answer: C. Rs. 85
Cost Price = Rs. 100. Loss = 15% of Cost Price = (15/100) * 100 = Rs. 15. Selling Price = Cost Price - Loss = Rs. 100 - Rs. 15 = Rs. 85.
