Simple interest on a certain sum at a certain annual rate of interest is 1/9 of the sum. If the numbers representing rate percent and time in years be equal, then the rate of interest is: | [
"2 2/3",
"None of these",
"8",
"3 1/3"
] | D | Explanation :
Let sum = x. Then, S.I. = x/9
Let rate = R% and time = R years.
[x * R * R / 100] = x / 9 ? R^2 = 100/9
R = 10/3 = 3 1/3.
Hence, time = 3 1/3 %.

A 300 metre long train crosses a platform in 39 seconds while it crosses a post in 18 seconds. What is the length of the platform? | [
"350 m",
"600 m",
"420 m",
"700 m"
] | A | Explanation:
Length of the train = distance covered in crossing the post = speed × time = speed × 18
Speed of the train = 300/18 m/s = 50/3 m/s
Time taken to cross the platform = 39 s
(300+x)/(50/3) = 39 s where x is the length of the platform
300+x = (39 × 50) / 3 = 650 meter
x = 650-300 = 350 meter

What term in physics refers to the use of force to move an object? | [
"work",

] | A | Work is defined differently in physics than in everyday language. In physics, work means the use of force to move an object. The teen who is playing tennis in Figure above is using force to move her tennis racket, so she is doing work. The teen who is studying isn’t moving anything, so she is not doing work. | SCiQ_train |

] | A | As you know, density is defined as the mass per unit volume of a substance. Since gases all occupy the same volume on a per mole basis, the density of a particular gas is dependent on its molar mass. A gas with a small molar mass will have a lower density than a gas with a large molar mass. Gas densities are typically ... | SCiQ_train |
The sides of a rectangular field are in the ratio 3 : 4. If the area of the field is 10800 sq. m, the cost of fencing the field @ 25 paise per metre is | [
"Rs. 55.50",
"None of these",
"Rs. 105.00",
"Rs. 86.50"
] | C | Solution
Let length = (3x) metres and breadth = (4x) metres.
Then, 3x × 4x = 10800 ⇔ 12x2 = 10800 ⇔ x2 =900 ⇔ x = 30.
So, length = 90 m and breadth = 120 m.
Perimeter = [2(90 + 120)] m = 420 m.
∴ Cost of fencing = Rs. (0.25 × 420) = Rs. 105.00. Answer D | AquaRat_train |

The percentage profit earned by selling an article for Rs. 1920 is equal to the percentage loss incurred by selling the same article for Rs. 1280. At what price should the article be sold to make 25% profit? | [
"2000",
"1200",
"1172",
"2797"
] | A | Explanation:
Let C.P. be Rs. x.
Then, (1920 - x)/x * 100 = (x - 1280)/x * 100
1920 - x = x - 1280
2x = 3200 => x = 1600
Required S.P. = 125 % of Rs. 1600 = 125/100 * 1600 = Rs. 2000.

The average of runs of a cricket player of 10 innings was 32. How many runs must he make in his next innings so as to increase his average of runs by 4 ? | [
"76",
"11",
"29",
"26"
] | A | Explanation:
Average = total runs / no.of innings = 32
So, total = Average x no.of innings = 32 x 10 = 320.
Now increase in avg = 4runs. So, new avg = 32+4 = 36runs
Total runs = new avg x new no. of innings = 36 x 11 = 396
Runs made in the 11th inning = 396 - 320 = 76

Total weight of the boys = 20x
After the boy weighing 34 kg joins the group, total weight of boys = 20x + 34
So 20x + 34 = 21(x + 1) = > x = 13.
