According to the question,
The compound interest on Rs 1,000/- at 10% per annum for 3 years (in Rs) is:
Rs. 1,331/-
Rs. 331/-
Rs. 300/-
^{Rs. 1,300/-}
B.
Rs. 331/-
∴ Required interest = Rs. (100 + 110 + 121) = Rs. 331
If then the value of is:
-2
0

,
Put the value of x = 1 as it satisfies the equation,
The average of 15 numbers is 7. If the average of the first 8 numbers is 6.5 and the average of the last 8 number is 8.5. then middle number is
10
23
13
15
D.
15
Sum of all 15 numbers = 15 x 7 = 105
Sum of first 8 numbers = 6.5 x 8 = 52
Sum of last 8 numbers = 8 x 8.5 = 68
∴ Required Middle Number = 52 + 68 - 105 = 120 - 105 = 15
A man travells of the distance of his journey by bus, by Rickshaw and 2 km on foot. The total distance travelled by the man is
12 km
18 km
20 km
24 km
D.
24 km
Distance travelled by foot:
According to the question,
^{}∴ Total distance travelled = (12 x 2) = 24 km

A whole number that can be divided exactly by numbers other than 1 or itself is called composite number.
Here are list of composite numbers till 100
Thus, between 67 and 101 there 27 such numbers.
A man bought 25 creates of oranges for Rs 10,000/-. He lost 5 crates. In order to earn a total profit of 25% of the total cost, he would have to sell each of the remaining crates at:
Rs 650/-
Rs 625/-
Rs 600/-
Rs 575/-
B.
Rs 625/-
Purchased crates = 25
Lost crates = 5
Net crates = (25 - 5) = 20 crates.
Let he sells remaining crates at Rs. x/-
