**On lending a certain sum of money on compound interest, one gets Rs.9050 in 2 years and Rs.9500 in 3 years. What is the rate of interest?**

**Answer:** Rate of interest(r):

r= (Y-X)*100/X

Y= Rs. 9500

X = 9050

On substituting values, r = 5%

**A mother is twice as old as her son. If 20 years ago, the mother’s age was 10 times the age of the son, what is the mother’s present age?**

**Answer:**

Let the age of the son = X years

∴age of the mother would be

=2X

As per the question 20 years

years ago;

10 (X -20) = 2X – 20

10X – 200 = 2X – 20

10X – 2X= – 20 + 200

8X = 180

X= 22.5 years

∴Age of mother = 22.5 * 2 = 45 years

**Two numbers are in the ratio 5:4. Shreya subtracts 12 from each. The new number is in the ratio of 4:3. Find the smaller number.**

**Answer:** Let the two numbers be 5x and 4x.

(5x – 12) ÷ (4x – 12) = 4 ÷ 3

3(5x – 12) = 4(4x – 12)

15x – 36 = 16x – 48

x = 12

The smaller number is 48.

**What is the probability of rolling a die and showing a multiple of three?**

**Answer:** sample space when you roll a die is:

S = (1, 2, 3, 4, 5, 6)

the probability when you roll a die is:

Total number of favorable outcomes ÷ Total number of outcomes

Probability = 2/6 = 1/3

**A train moving at 80 km/hr speed crosses a pole in 7 seconds. Find the length of the train.**

**Answer:**

find the distance travelled by train in 7 seconds by applying the following formula:

Distance= Speed x Time

Speed is given in Km/hr so we will convert it into m/s as answers are given in meters.

Speed=90* 5/18= 25 m/s

Time = 7 seconds

Distance = 25 * 7= 175 meters

**A group of 15 students learning foreign languages. 7 of them have studied Latin, 8 are students of Greek, and 3 in the group have not studied either language. How many students have studied both languages?**

**A right triangle with sides 3 cm, 4 cm, and 5 cm is rotated on the side of 3 cm to form a cone. The volume of the cone so formed is:**

**Answer:** *r* = 3 cm and *h* = 4 cm.

using 1/3(pi*r*² h), we get 12pi cm³ as the volume

**A clock shows 8 a.m. Through how many degrees will the hour hand rotate when the clock shows 2 p.m.?**

**Answer:** (360*6)/12 = 180 degrees

**How many times are the hands of a clock at a right angle in a day?**

**Answer:** They are at 22 right angles in 12 hours.

**Answer**:

value of the share = Rs. 100

**3 pumps operate 8 hours a day and can empty a tank in 2 days. How many hours a day must 4 pumps work to empty the tank in 1 day?**

**Answer:**

Let the number of working hours per day be x.

Fewer days, More working hours per day

4 x 1 x x = 3 x 2 x 8

x = 12.

**With 7 constants and 4 vowels, find out how many words of 3 constants and 2 vowels can be formed.**

**Answer:**

when we combine 3 consonants and 2 vowels out of 7 consonants and 4 vowels, using combinations

^{7}C_{3} * ^{4}C_{2} = = 210

Every group consists of 5 words hence the possible arrangement of the letters is 5!

Or, 5! = 120 ways.

The required number of words = 210*120 = 25200.

**The cost of ten apples, eight kiwis, and 12 papayas is ₹240. It is given to you that the cost of eight apples, six kiwis, and ten papayas is ₹ 180. Find the cost of one apple, one kiwi, and one papaya.**

**Answer:** let cost of apple = x, kiwi = y, papaya = z

according to the question

10x + 8y + 12z = 240

8x + 6y + 10z = 180

Solve these equations

x + y + z = 30

thus the cost of one apple, one kiwi, and one papaya is 30.

**Find out in how many different ways can the letters of the word ‘LEADING’ be arranged in a way so that the vowels come together always.**

**Answer:**

When the vowels EAI are always together, they can form one letter.

now we have to arrange the letters LNDG apart from (EAI).

5 i.e (4 + 1 = 5) letters can be arranged in 5! = 120 ways.

The vowels (EAI) can be arranged in 3! = 6 ways.

hence required number of ways for our required arrangement = (120 x 6) = 720.

**Find the odd one out in the series: 53, 59, 61, 73, 79, 87, 89**

**Answer:** 87 because the other numbers are prime numbers, but 87 has other factors.

**It is given that the speed of a boat in still water is 5km/hr. If the speed of the boat against the stream is 3 km/hr, what is the speed of the stream?**

**Answer:**

Suppose the speed of the stream is X km/hr

The speed of the boat is 5 km/hr

Speed upstream is given to be 3km/hr

Speed upstream = speed of the boat – speed of the stream

3 = 5 – X

X = 5 – 3 = 2 km/hr

**Find the value of 5**^{1/4}x (125)^{25}

**Answer**:

5^{1/4} x (125)^{0.25}

5^{1/4} × (5^{3} )^{1/4}= 5

**How can the letters of the word “RUMOUR” be arranged?**

**Answer**:

Required number of permutations =

Or, = 180

180 words can be formed.

**Find how many numbers can be formed from the digits 2, 3, 4, 5, 6, and 7 which are divisible by 5 in such a way that digits do not repeat.**

**Answer**:

A number is divisible by 5 only if it ends with 0 or 5, since we don’t have 0 in the given digits that means 5 should come at the unit place.

The remaining 5 digits (2, 3, 4, 6, and 7) can come at the tens place.

In the same way, fill the hundreds place with one of the remaining 4 digits.

The thousands place can be filled by one of the remaining 3 digits.

Therefore, the required number of the numbers = 1**5**4*3 = 60.
