Correct Option: D) The Dalai Lama
The quote "In the practice of tolerance, one's enemy is the best teacher" is a well-known saying by the 14th Dalai Lama, Tenzin Gyatso. It reflects the Buddhist principle that challenges and difficult individuals provide opportunities for spiritual growth and the development of virtues like patience and tolerance.
The question asks to identify what "Shigmo" is. This requires general knowledge about Indian festivals and cultural terms.
A) A Goan Spring Festival
Shigmo, also known as Shigmotsav, is indeed a prominent Hindu spring festival celebrated in Goa, India. It is a festival of vibrant colours, traditional folk dances (like Ghodemodni and Fugdi), music, and parades, marking the arrival of spring and celebrating the harvest.
The question asks to identify what the listed names (Yosemite, Mavericks, Mountain Lion, Lion, Snow Leopard, Leopard, Tiger, Panther, Jaguar, Puma, and Cheetah) represent in the context of computers. This requires knowledge of operating system history, specifically Apple's Mac OS X.
A) Versions of Mac OS X. The listed names are all well-known codenames or official release names for different versions of Apple's Mac OS X (later OS X and macOS) operating system.
Rearrange the jumbled letters to make a meaningful word and then select the one which is different.
The problem requires us to first rearrange the jumbled letters in each option to form a meaningful English word. After forming the words, we need to identify which one is different from the others based on a common characteristic or category.
Therefore, PIPE is the word that is different from the others.
C) EPPI — Rearranging 'EPPI' gives 'PIPE'. 'PIPE' is an object, whereas 'NINE', 'ONE', and 'THREE' (from options A, B, and D respectively) are all numbers. Hence, 'PIPE' is the odd one out.
Solve: \( \frac{12}{13} \) × \( \frac{285}{96} \) ÷ \( \frac{171}{169} \) = ?
3 \( \frac{2}{3} \)
2 \( \frac{17}{24} \)
\( \frac{7}{8} \)
\( \frac{11}{24} \)
To solve this problem, we need to perform the multiplication and division of fractions. The key steps involve converting division into multiplication by taking the reciprocal of the divisor, simplifying the fractions by canceling common factors, and then performing the multiplication.
First, write down the given expression:
\[ \frac{12}{13} \times \frac{285}{96} \div \frac{171}{169} \]Convert the division operation into multiplication by inverting the fraction that follows the division sign:
\[ \frac{12}{13} \times \frac{285}{96} \times \frac{169}{171} \]Now, simplify the fractions by looking for common factors between numerators and denominators. We can simplify step by step:
Simplify \(\frac{12}{96}\): Both are divisible by 12. \(12 \div 12 = 1\) and \(96 \div 12 = 8\). So, \[\frac{12}{96} = \frac{1}{8}\].
Simplify \(\frac{169}{13}\): \(169 = 13 \times 13\). So, \(\frac{169}{13} = 13\).
Simplify \(\frac{285}{171}\): Both are divisible by 3 (sum of digits of 285 is 15, sum of digits of 171 is 9). \(285 \div 3 = 95\) and \(171 \div 3 = 57\). So, \[\frac{285}{171} = \frac{95}{57}\].
Now the expression becomes:
\[ \frac{1}{1} \times \frac{95}{8} \times \frac{13}{57} \]Further simplify \(\frac{95}{57}\): Both are divisible by 19. \(95 \div 19 = 5\) and \(57 \div 19 = 3\). So, \[\frac{95}{57} = \frac{5}{3}\].
The expression is now:
\[ \frac{1}{1} \times \frac{5}{8} \times \frac{13}{3} \]Multiply the remaining numerators and denominators:
\[ \frac{1 \times 5 \times 13}{1 \times 8 \times 3} = \frac{65}{24} \]Convert the improper fraction to a mixed number. Divide 65 by 24:
\(65 \div 24 = 2\) with a remainder of \(65 - (2 \times 24) = 65 - 48 = 17\).
So, \[\frac{65}{24} = 2 \frac{17}{24}\].
B) The calculated result is \(2 \frac{17}{24}\), which matches option B.
