Puja Tiwari answered |
The pattern followed is:
A = 1 so, 12 = 1 so, 1 = A.
B = 2 so, 22 = 4 so, 4 = D.
C = 3 so, 32 = 9 so, 9 = I.
D = 4 so, 42 = 16 so, 16 = P ≠ R
E = 5 so, 52 = 25 so, 25 = Y.
So, the wrong term is DR.

The emitter region in N-P-N junction transistor is more heavily doped than the base region because it serves to inject a large number of charge carriers into the base, which then travels into the collector so that switching or amplification can occur.

यूएस तकनीकी दिग्गज ऐपल 2022 में $3tn (£2.2tn) के स्टॉक मार्केट मूल्यांकन तक पहुँचने वाली पहली कंपनी बन गई।
कंपनी के शेयर की कीमत 2007 में सह-संस्थापक और पूर्व सीईओ स्टीव जॉब्स द्वारा पहले आईफोन के अनावरण के बाद से लगभग 5,800% बढ़ी है।
ऐपल महामारी के दौरान बड़े विजेताओं में से एक रहा है, क्योंकि कोरोनावायरस लॉकडाउन ने गैजेट्स पर खर्च बढ़ा दिया।
ऐपल के स्टॉक मार्केट मूल्यांकन को $2tn से $3tn तक बढ़ने में केवल 16 महीने से थोड़ा अधिक समय लगा।
कंपनी अगस्त 2018 में $1tn के स्टॉक मार्केट मूल्यांकन तक पहुँचने वाली पहली कंपनी बनी।

1 / 43.21 = 0.02314
दोनों पक्षों को 105 से गुणा करने पर,
105 / 43.21 = 0.02314 x 105
1 / (43.21 / 100000) = 2314
इसलिए, 1 / 0.0004321 = 2314 है।
इस प्रकार, उत्तर विकल्प 2 सही है।

|
G.K Academy answered |
Let the speed of boat in still water be x km/hr and the rate of stream be y km/hr
Downstream rate = (x + y) km/hr and upstream rate = (x – y) km/hr
Now, 20 /x + y = 1
⇒ x + y = 20 .....(1)
and 20/x - y = 2
⇒ x - y = 10 .....(2)
From (1) and (2) we have x = 15 km/hr
Downstream rate = (x + y) km/hr and upstream rate = (x – y) km/hr
Now, 20 /x + y = 1
⇒ x + y = 20 .....(1)
and 20/x - y = 2
⇒ x - y = 10 .....(2)
From (1) and (2) we have x = 15 km/hr

Understanding Work Rates
To determine how long X and Y will take together to complete 5/9 of the total work, we first need to calculate their individual work rates.
Work Rate of X
- X can complete the work in 12 days.
- Therefore, X's work rate = 1/12 of the work per day.

20

|
Pallabi Datta answered |
Let selling price of 1 chair = S.P
Cost price of 1 chair = C.P
Profit in selling 250 chairs = 50 S.P
Profit in selling 1 chair = 50/250 S.P = 0.2 S.P
Profit = S.P - C.P
⇒ 0.2 S.P = S.P - C.P
⇒ C.P = 0.8 S.P
Profit percentage = (profit/C.P) × 100 = (0.2 × S.P/0.8 × S.P) × 100 = 25%

Gaurav Chavan answered • Dec 05, 2024 |
Understanding the Statement
The statement suggests that a student with average intelligence can attempt aptitude questions, provided they have an interest in Mathematics. This highlights two aspects: intelligence and interest.
Analyzing the Inference
The inference drawn is that "Intelligence of the Student can be assessed by his interest towards Mathematics."
... more
- Intelligence vs. Interest
- Intelligence is a measure of cognitive abilities and problem-solving skills.
- Interest in a subject, such as Mathematics, does not necessarily correlate with intelligence. A student may be highly interested in Mathematics but not possess above-average intelligence.
- Limitations of the Inference
- Interest can influence performance but is not a definitive measure of intelligence.
- A student may excel in Mathematics due to factors like motivation, teaching quality, or personal experiences, independent of their innate intelligence.
- Conclusion
- The inference incorrectly links interest in Mathematics as a direct indicator of intelligence. Therefore, labeling it as true is misleading.
Final Answer
Given this analysis, the correct answer is option 'B' (False), as the inference does not hold true based on the relationship between interest and intelligence.

Gaurav Chavan answered • Nov 19, 2024 |
Understanding the Problem
To solve how much of the tank will be filled after 6 hours with taps A, B, and C working together, we first need to determine the rate at which each tap works.
Rates of Taps
- Tap A: Fills the tank in 9 hours.
- Rate = 1/9 tank per hour
- Tap B: Fills the tank in 6 hours.
- Rate = 1/6 tank per hour
- Tap ... more: Empties the tank in 4 hours.
- Rate = -1/4 tank per hour (negative because it empties)
Combined Rate
Now, we add the rates of all three taps:
- Combined Rate = Rate of A + Rate of B - Rate of C
- Combined Rate = (1/9 + 1/6 - 1/4)
To combine these fractions, we first find a common denominator, which is 36.
- (1/9 = 4/36)
- (1/6 = 6/36)
- (1/4 = 9/36)
So, we have:
- Combined Rate = (4/36 + 6/36 - 9/36) = (4 + 6 - 9) / 36 = 1/36 tank per hour
Calculating Total Filled in 6 Hours
Now, we calculate how much of the tank is filled in 6 hours:
- Amount filled in 6 hours = Combined Rate × Time
- Amount filled = (1/36) × 6 = 6/36 = 1/6
Conclusion
After 6 hours, the portion of the tank that will be filled is 1/6.
Therefore, the correct answer is option 'C'.

- (1/6 = 6/36)
- (1/4 = 9/36)
So, we have:
- Combined Rate = (4/36 + 6/36 - 9/36) = (4 + 6 - 9) / 36 = 1/36 tank per hour
Calculating Total Filled in 6 Hours
Now, we calculate how much of the tank is filled in 6 hours:
- Amount filled in 6 hours = Combined Rate × Time
- Amount filled = (1/36) × 6 = 6/36 = 1/6
Conclusion
After 6 hours, the portion of the tank that will be filled is 1/6.
Therefore, the correct answer is option 'C'.

Atomicity requires that each transaction be "all or nothing". The consistency property ensures that any transaction will bring the database from one valid state to another.
