Too much, too many with a noun

- প্রায়শই আমরা much and many এর পূর্বে too  ব্যবহার করে থাকি। এদের সাধারণ অর্থ: ‘more than necessary’
- We can use too much before an uncountable noun and too many before a plural noun, or without a noun when the noun is obvious:
যেমন: 
- I bought too much food. We had to throw some of it away.
- They had a lot of work to do. Too much. (too much work)

প্রদত্ত প্রশ্নে যেহেতু টাকা uncountable noun সুতরাং এর পূর্বে too much  বসাটাই যুক্তিযুক্ত।
