Question: Anne is 2 times as tall as her sister while Bella is 3 times as tall as Anne. If Anne is 80cm tall, what is the height difference between Bella and Anne's sister?
Answer: Anne is 2 times as tall as her sister hence 2 * (her sister's height) = 80cm. Her sister's height = 80cm / 2 = 40cm. Bella is 3 times as tall as Anne hence Bella's height is 3 * 80 cm = 240 cm. The height difference between Bella and Anne's sister = 240 - 40 = 200cm. The answer is 200.
[Question]The dinner bill for 6 friends came to $150. Silas said he would pay for half of the bill and the remaining friends could split the rest of the bill and leave a 10% tip for the whole meal. How many dollars will one of the friends pay?
[Answer]Silas paid half = 150 / 2 = 75. Remaining bill paid by 5 friends = 75 + 10% of 150 = 75 + 15 = 90. Each person will pay 1 / 5 which is 90 / 5 = 18. Each friend will pay $18. The answer is 18.
[Question]The cost of transporting 80 bags of cement, each weighing 50 kgs, is $6000. What's the cost of transporting three times as many cement bags, each weighing 3/5 times as many kgs?
[Answer]
Three times as many cement bags is 3 * 80 = 240 cement bags. If a bag of cement weighs 50 kg, 3 / 5 times as much weight is 3 / 5 * 50 = 30 kgs. If the cost of transporting 80 bags of cement, each weighing 50 kgs, is $6000, the cost of transporting one bag of cement weighing 50 kg is $6000 / 80 = $75. Since a bag weighing 50 kgs costs $75 to transport, a bag weighing 30 kgs will cost 30 * $75 / 50 = $45 to transport. The cost of transporting 240 cement bags each weighing 30 kgs is $45 * 240 = $10800. The answer is 10800.
