22218.	Compute cost of goods sold for the year 2017:
Answer» Calculation of cost of goods sold for the year 2017: Cost of goods sold = opening stock + Purchased + Direct expenses – closing stock = 30,000 + 1,50,000 + (10,000 + 10,000) – 40,000 = 30,000 + 1,50,000 + 20,000 – 40,000 = 2,00,000 – 40,000 Cost of goods sold = Rs. 1,60,000 Note: Direct expenses includes both wages as well as carriage inwards.

22218.

Compute cost of goods sold for the year 2017:

Answer»

Calculation of cost of goods sold for the year 2017:

Cost of goods sold = opening stock + Purchased + Direct expenses – closing stock

= 30,000 + 1,50,000 + (10,000 + 10,000) – 40,000

= 30,000 + 1,50,000 + 20,000 – 40,000

= 2,00,000 – 40,000

Cost of goods sold = Rs. 1,60,000

Note: Direct expenses includes both wages as well as carriage inwards.

Answer» (sin 78° - sin 42°) - (sin 66° + sin 6°) By applying sin rule: 2 cos60° sin18° - 2 cos36° sin30° 2 x 1/2 sin18° - 2 cos 36 x 1/2 sin 18° - cos 36° sin 18° - sin 54° Again, - ( sin 54° - sin 18°) - 2cos(36) sin(18) Also, we know sin(36) = 2 sin(18)cos(18) sin(18)=sin(36)/(2cos(18)) thus, sin(54)−sin(18) = cos(36) sin(36) / cos(18) = cos(36) sin(36) / sin (72) sin(54)−sin(18)= cos(36) sin(36) / 2 sin(36) cos(36) = 1/2 - ( sin 54° - sin 18°) = - 1/2 sin(72

Push-ups are a fast and effective exercise for building strength. These are helpful in almost all sports including athletics. While the push-up primarily targets the muscles of the chest, arms, and shoulders, support required from other muscles helps in toning up the whole body.Nitesh wants to participate in the push-up challenge. He can currently make 3000 push-ups in one hour. But he wants to achieve a target of 3900 push-ups in 1 hour for which he practices regularly. With each day of practice, he is able to make 5 more push-ups in one hour as compared to the previous day. If on first day of practice he makes 3000 push-ups and continues to practice regularly till his target is achieved. Keeping the above situation in mind answer the following questions:(i) Form an A.P representing the number of push-ups per day and hence find the minimum number of days he needs to practice before the day his goal is accomplished?(ii) Find the total number of push-ups performed by Nitesh up to the day his goal is achieved.

Answer»

(i) 3000, 3005, 3010, ...,3900.

a_n = a + (n - 1)d

3900 = 3000 + (n - 1)5

⇒ 900 = 5n − 5

⇒ 5n = 905

⇒ n = 181

Minimum number of days of practice = n - 1 = 180 days

(ii) S_n = \(\frac{n}{2}\)(a + l)

= \(\frac{181}{2}\) × (3000 + 3900) = 624450 pushups

\(\int_0^1x\,dx\)

= \([\frac{x^2}{2}]^1_0\)

= \(\frac{1}{2}\) - 0

Answer»

1/1+n^3 +4/n^3+1

put n equal to 1/0 then 1/1+{1/0}^3

0/1

then answer is D

n(n+1)(2n+1)/6(n³+1)

(2n²+ n)/(6n²-6n+6)

(2+1/n)/(6-6/n+6/n²)

n=infinity

==2/6=1/3

22248.	How many calcium ions diffuse across a pre-synaptic membrane at a time?
Answer» 1. Calcium (Ca₂⁺)is a vital element in the process of neurotransmitter release; when Ca2+channels are blocked, neurotransmitter release is inhibited. 2. These consist of multi-protein complexes that tether the synaptic vesicle to the presynaptic membrane and contain high concentrations of voltage-gated calcium channels. 3. This leads to brisk calcium influx in response to axon terminal depolarization, since the concentration of calcium is 10,000 times higher in the extracellular fluid.
