Moscow officials said that a pair of Russian astronauts cut out the material samples around a spy hole in a Soyuz spacecraft stationed at the International Space Station on Tuesday using knives and chin knives. It was discovered in August, after the last trip of the spacecraft, that the 2-meter pipe airbag on the Soyuz spacecraft was parked at international space. The Rascassasmos Space Agency said that the small but dangerous hole had been found on Earth or in the outer space was to cut the enclosed glue material, to analyze the model of the material and to pull it into a new tapper in that area.
Senior astronauts fought and ultimately succeeded in their pursuit. Before this astronaut walk, the spacecraft could only examine the hole within the spacecraft. Unlike the International Space Station, the Soyce shuttle was not designed to repair and hold the spacecraft in the outer space, but did not have any of the handles to hold. The claim was that astronauts had cut the glue around the hole, but failed to collect the sample to analyze Arkal.
Select the correct answer from the following
A - The claim is entirely correct

There are three types of old coins in a box at 3: 5: 7. The value of old currencies is 1 rupee, 5 rupees and 10 rupees respectively. The total value of the coins in the box is Rs. If 2450, find the number of coins worth 10 rupees.
Solution
Let number of 1 rupee, 5 rupees and 10 rupees respectively be $$3x,5x$$ and $$7x$$
Total amount = $$(1\times3x)+(5\times5x)+(10\times7x)=2450$$
=> $$3x+25x+70x=2450$$
=> $$x=\frac{2450}{98}=25$$
$$\therefore$$ Number of 10 rupees coins = $$7\times25=175$$

After subsequent discounts of 10% and 20%, the sale price of a product is Rs. 1,836. If its modest price is 50% of the price at which the subject is priced, what is its suppression price? (In Rupees)
Solution
Let modest price = Rs. $$100x$$
After 1st discount of 10%, selling price = $$100x-(\frac{10}{100}\times100x)=Rs.$$ $$90x$$
Similarly, after 2nd discount of 20%, selling price = $$90x-(\frac{20}{100}\times90x)=Rs.$$ $$72x$$
According to ques, => $$72x=1836$$
=> $$x=\frac{1836}{72}=25.5$$
$$\therefore$$ Suppression price = $$\frac{50}{100}\times100\times25.5=Rs.$$ $$1275$$

The difference between the compound interest and the interest rate for a certain amount invested in 2 years is Rs. Is 198. If the interest rate is 6% per annum, find out the amount invested.
Solution
Rate of interest = 6% and time period = 2 years
Let principal sum = Rs. $$P$$
Also, difference between compound interest and simple interest for 2 years = $$P(\frac{r}{100})^2$$
=> $$P(\frac{6}{100})^2=198$$
=> $$P=198\times\frac{10000}{36}$$
=> $$P=Rs.$$ $$55,000$$

A 145-meter long train passes at 54 kilometers and crosses a bridge in 29 seconds. If so, find the length of the bridge. (In meters)
Solution
Speed of train = 54 kmph = $$54\times\frac{5}{18}=15$$ m/s
Let length of bridge = $$x$$ m
Using, speed = distance/time
=> $$15=\frac{145+x}{29}$$
=> $$145+x=29\times15=435$$
=> $$x=435-145=290$$ m
