If the sum of money is divided among ‘n’ children, each child will receive $60. If another child is added to the group and the amount is distributed again each child will receive $50. What is the sum of money to be distributed?
Let the money be = Y
If the sum of money is divided among ‘n’ children, each child will receive $60
Y ÷ n = 60 Y = 60n (eqn 1)
If another child is added to the group and the amount is distributed again each child will receive $50
Y ÷ (n+1) = 50 Y = 50 * (n+1) Y = 50n + 50 (eqn 2)
putting (eqn 1) into (eqn 2) 60n = 50n + 50 60n - 50n = 50 10n = 50 n = 50 ÷ 10 n = 5
Remember "n" is the number of children, but the question says What is the sum of money to be distributed?. So what will are looking for is Y, not "n".

From (eqn 1) Y = 60n Y = 60 * 5 Y = 300
Answer: $300

China’s stock markets are some of the largest in the world, with total market capitalization reaching RMB 79 trillion (US$12.2 trillion) in 2020. China’s stock markets are seen as a crucial tool for driving economic growth, in particular for financing the country’s rapidly growing high-tech sectors.Although traditionally closed off to overseas investors, China’s financial markets have gradually been loosening restrictions over the past couple of decades. At the same time, reforms have sought to make it easier for Chinese companies to list on onshore stock exchanges, and new programs have been launched in attempts to lure some of China’s most coveted overseas-listed companies back to the country.
How to Buy Bitcoin?
Most people buy Bitcoin via exchanges, such as Coinbase. Exchanges allow you to buy, sell and hold cryptocurrency, and setting up an account is similar to opening a brokerage account—you’ll need to verify your identity and provide some kind of funding source, such as a bank account or debit card. Major exchanges include Coinbase, Kraken, and Gemini. You can also buy Bitcoin at a broker like Robinhood. Regardless of where you buy your Bitcoin, you’ll need a digital wallet in which to store it. This might be what’s called a hot wallet or a cold wallet. A hot wallet (also called an online wallet) is stored by an exchange or a provider in the cloud. Providers of online wallets include Exodus, Electrum and Mycelium. A cold wallet (or mobile wallet) is an offline device used to store Bitcoin and is not connected to the Internet. Some mobile wallet options include Trezor and Ledger.
