SI = (5000 × 10 × 2)/100 = 1000. CI = 5000(1.1)² - 5000 = 5000(1.21 - 1) = 1050. Difference = 1050 - 1000 = 50.

a:b = 3:4 means a/b = $\frac{3}{4}$. b:c = 5:6 means b/c = $\frac{5}{6}$. a/c = (a/b) × (b/c) = ($\frac{3}{4}$) × ($\frac{5}{6}$) = $\frac{15}{24}$. So a:c = 15:24.

Using Pythagorean theorem: distance = √(10² + 15²) = √(100 + 225) = √325 km ≈ 18.03 km.

Using formula: LCM × GCD = Product of numbers. 120 × 10 = 40 × x. 1200 = 40x. x = 30.

Let number = x. 0.4x = 96. x = 240. 65% of 240 = 0.65 × 240 = 156.

Rate of A+B = $\frac{1}{8}$. Rate of A = $\frac{1}{12}$. Rate of B = $\frac{1}{8}$ - $\frac{1}{12}$ = $\frac{3}{24}$ - $\frac{2}{24}$ = $\frac{1}{24}$. B takes 24 days.

Let CP = 100. MP = 150. SP = 150 × 0.8 = 120. Profit = 120 - 100 = 20. Profit% = 20%.

(x + 1/x)² = x² + 2 + 1/x² = 25. Therefore, x² + 1/x² = 25 - 2 = 23.

Original speed = $\frac{240}{4}$ = 60 km/h. New speed = 60 × 1.25 = 75 km/h. Time = $\frac{240}{75}$ = 3.2 hours = 3 hours 12 minutes

Let CP = x. Then 15x = 12 × SP, so SP = 1.25x. Profit% = (SP - CP)/CP × 100 = (1.25x - x)/x × 100 = 25%

Let numbers be 2x, 3x, 5x. Sum = 2x + 3x + 5x = 10x = 150. So x = 15. Largest number = 5x = 75

Work rate of person A = $\frac{1}{12}$ per day, person B = $\frac{1}{18}$ per day. Combined rate = $\frac{1}{12}$ + $\frac{1}{18}$ = $\frac{5}{36}$ per day. Work by A alone in 5 days = $\frac{5}{12}$. Remaining work = 1 - $\frac{5}{12}$ = $\frac{7}{12}$. Days together = ($\frac{7}{12}$)/($\frac{5}{36}$) = ($\frac{7}{12}$) × ($\frac{36}{5}$) = 4.2 ≈ 4 days

The sentence uses active voice as the subject 'committee' performs the action 'decided'.

'Receive' is the correct spelling. Remember the rule: 'i' before 'e' except after 'c'.

'Ephemeral' means short-lived or temporary. 'Transient' has the same meaning.

Direct questions should be enclosed in quotation marks and end with a question mark inside the quotes.

'Quickly' modifies the verb 'ran' by describing how the action was performed, making it an adverb.

'Caustic' means sarcastic and harsh, which fits the context of offending people. Other options suggest positive qualities.

'News' is an uncountable noun and takes singular verb 'is', not 'are'.

'Meticulous' means showing great attention to detail. 'Careless' is its direct opposite.
