Explanation

The pattern in the series is as follows:

9 + 1 = 10

10 + 3 = 13

13 + 6 = 19

The next difference should be +9:

19 + 9 = 28

So, the correct answer is 28.

Explanation

To evaluate this expression, we need to follow the order of operations (PEMDAS):

• Divide 3 by 1/3: 3 ÷ 1/3 = 3 × 3 = 9
• Subtract 9 from 9: 9 - 9 = 0
• Add 1 to 0: 0 + 1 = 1

So, the solution to the equation is 1.

Explanation

To find the market price of the car without tax, we need to remove the 6% sales tax from the total price of Rs. 154,431.40.

Let the market price of the car be P.

Including 6% sales tax, the equation is:

P + 0.06P = 154,431.40

1.06P = 154,431.40

Now, solve for P:

P = 154,431.40/1.06

P = 145,690

So, the market price of the car without tax is Rs. 145,690.

Explanation

The alphabets follow a pattern:

$C+2=E$

$E+3=H$

$H+4=L$

$L+5=Q$

$Q+6=W$

$W+7=D$

Hence, $D$ replaces the question mark.

Explanation

The formula for the volume of a rectangular prism is:

Volume = Length × Width × Height

In this case, the length, width, and height are all 3 cubic inches, so:

Volume = 3 × 3 × 3 = 27 cubic inches

Therefore, the volume is 27 cubic inches.

Explanation

To find the duration of the train journey, subtract the start time from the arrival time:

Arrival time: 5:23 p.m.

Start time: 9:32 a.m.

Convert both times to a 24-hour clock:

Arrival time: 17:23 (5:23 p.m.)

Start time: 09:32 (9:32 a.m.)

Subtract the start time from the arrival time:

17:23 - 09:32 = 7 hours 51 minutes

Therefore, the train journey took 7 hours and 51 minutes.

Explanation

To calculate the interest, you can use the formula:

Interest = Principal × Rate × Time

In this case:

Principal (P) = Rs. 500

Rate (R) = 11% per annum = 0.11

Time (T) = 4 years

Interest = 500 × 0.11 × 4 = Rs. 220

So, Mr. Ali has to pay back the principal amount of Rs. 500 plus the interest of Rs. 220, making a total of Rs. 720.

The correct answer is: Rs. 220

Explanation

Ali's current age is 32.

His son's current age is 0 (newborn).

We want to find the number of years it takes for Ali's age to be 5 times his son's age.

Let's assume the number of years is x.

After x years, Ali's age will be: 32 + x

And his son's age will be: 0 + x = x

We want Ali's age to be 5 times his son's age, so we set up the equation: 32 + x = 5x

Subtracting x from both sides: 32 = 4x

Dividing both sides by 4: 8 = x

Therefore, it will take 8 years for Ali's age to be 5 times his son's age.

The correct answer is 8 years.

Explanation

To evaluate this expression, we need to follow the order of operations (PEMDAS):

Subtract 216 from 616: 616 - 216 = 400

Add 216 to 400: 400 + 216 = 616

So, the correct answer is 616.

Explanation

Total = 14,280

First 3,000 => 2% = 3000 x 2/100 =     60

Second 3,000 => 3% = 3000 x 3/100 = 90

Third 3,000 => 3% = 3000 x 3/100 =   90

Remaining 14,280 – 9000 = 5280 => 5280 x 4% = 211.20

Total Tax = 60 + 90 +90 +211.20 =

451.20
