Arun bought a computer with 15% discount on the labeled price. He sold the computer for $2880 with 20% profit on the labeled price. At what price did he buy the computer? | [
"$2420",
"$2040",
"$2310",
"$2440"
] | B | SP = 2880
Arun sold the computer with 20% profit on the Labeled Price
⇒2880=(120×Labeled Price) / 100
⇒Labeled Price=(2880×100)/120=28800/12=96004=2400
Arun bought a computer with 15% discount on the labeled price
=> CP = (Labeled Price×85) / 100=(2400×85) / 100=24×85=2040

Vishal and Raghu jointly started a business. Vishal invested three times as Raghu did and invested his money for double time as compared to Raghu. Raghu earned Rs. 4000. If the gain is proportional to the money invested and the time for which the money is invested then the total gain was ? | [
"Rs. 28,000",
"Rs. 8,000",
"Rs. 14,000",

Investments ratio is = 3:1
Time period ratio is = 2:1
As they are proportional to gain
------
Gain ratio of Vishal and raghu = 6:1
But given Raghu got Rs. 4000,
=? 1 ----- 4000
7 ----- ?
=> Rs.28,000
The total gain = Rs.28,000

To solubilize the fats so that they can be absorbed, what organ secretes a fluid called bile into the small intestine? | [
"gall bladder",

] | A | A related mechanism allows us to absorb and digest the fats in buttered popcorn and French fries. To solubilize the fats so that they can be absorbed, the gall bladder secretes a fluid called bile into the small intestine. Bile contains a variety of bile salts, detergent-like molecules that emulsify the fats. | SCiQ_train |

We can plug anything in for x and get a result. You can find f(1), for example, by plugging in 1 where x is, and you would get 12 - 1/2 = 11.5. Or we could find f(2), which would be 12 - 4/2 = 10.

Three persons invested Rs.9000 in a joint business. The second person invested Rs.1000 more than the first and the third Rs.1000 more than second. After two years, they gained Rs.3600. How much third person will get? | [
"2872",
"2980",
"2400",
"1600"
] | D | First persons investment = x
Second persons investment = x + 1000
Third persons investments = x + 2000
x + x + 1000 + x + 2000 = 9000
3x = 6000
x = 2000
Ratio = 2000 : 3000 : 4000

Local kennel has cats and dogs in the ratio of 6:12. If there are 24 fewer cats than dogs, how many dogs are in the kennel? | [

"52",
"54",

] | A | Lets work with the data given to us. We know that there ratio of cats to dogs is 6:12 or
cats 6
dogs 12
we can write number of cats as 6x and number of dogs as 12x and we know that 12x-6x= 24(therefore 6x = 24 => x=4)
Then # of dogs = 12x4= 48
