To form the code of a word, the first letter of the word is replaced by its successor, the second letter is replaced by its second successor, the third letter by its third successor and so on as per the English alphabetical series.

Similarly, we can find the code for the word VXMJ,

Hence, "WZPN" is the code for the word VXMJ.

Given:

a3 - b3 = 125

a2 - b2 = 25

a + b = 5

Formulas used:

a2 - b2 = (a + b) (a - b)

a3 - b3 = (a - b) (a2 + ab + b2)

Calculation:

a2 - b2 = 25

⇒ (a + b)(a - b) = 25

⇒ 5(a - b) = 25

⇒ (a - b) = 5

a3 - b3 = 125

⇒ (a - b) (a2 + ab + b2) = 125

⇒ 5 × (a2 + ab + b2) = 125

⇒ (a2 + ab + b2) = 125/5 = 25

∴ The value of (a2 + ab + b2) is 25

Given:

The greatest number that will divide 155, 260, 315 and leave the remainder 5, 10 and 15

Calculation:

In order to make 155, 260, and 315 divisible by the greatest number, we need to subtract 5, 10, and 15 from each term respectively.

155 - 5 = 150, 260 - 10 = 250, 315 - 15 = 300

Now HCF of 150, 250 and 300:

150 = 2 × 3 × 5 × 5

250 = 2 × 5 × 5 × 5

300 = 2 × 2 × 3 × 5 × 5

Hence, HCF of 150, 250 and 300 = 50

∴ The greatest number that will divide 155, 260 and 315 and leave the remainder 5, 10 and 15 respectively is 50.

Concept:

Mode = It is a number that is present most often in a given set of numbers. For example, a manufacturer wants to know the size of shoes that has maximum demand. Here, Mode is the most appropriate measure. However, it doesn't represent all the numbers or items in a given set.

Median = It is the middle element when the data set is arranged in order of the magnitude (from lower to higher). It remains unchanged if, there is any change in the largest or smallest item.

Range = It is the difference between the largest and smallest values in a given set of number.

Mean = Mean or Arithmetic mean is the most commonly used average. It is based on all the observations or given set of numbers.

∴ Measure of central tendency or average are used to summarize the data and mean is the most appropriate average value in measuring central tendency as it represents all the items in a given set of data.

Formulas used:

sec (90 - x) = cosec x

cot (90 - x) = tan x

Calculation:

5 sin 14° sec 76° + 3 cot 15° cot 75° + 2 tan 45°

⇒ 5 sin 14° cosec 14° + cot 15° tan 15° + 2 × 1 [tan 45° = 1]

⇒ 5 sin 14° . 1/sin 14° + 3 cot 15 . 1/cot 15° + 2 [cosec x = 1/sin x]

⇒ 5 + 3 + 2 [cot x = 1/tan x]

∴ The required result = 10

Given:

Total students in the class sponsored the musical programme = 50 girls + 70 boys = 120

Calculation:

No of girls attended the programme = 50 × 40/100 = 20

No of boys attended the programme = 70 × 50/100 = 35

According to the question,

⇒ (20 + 35)/120 x 100

⇒ 45.83% or 46%

∴ The required percentage of class is 46%

Calculation:

Let the length of the rope be = 20 units

So, length of the first part = 20 × 1/5 = 4 units

Length of the second part = 20 × 1/5 × 3/2 = 6

⇒ Length of the third part of the rope = 20 - 4 - 6 = 10 units

∴ Fraction of third part out of the whole rope = 10 units /20 units = 1/2

Given:

 5 2/3+ 0.73 - 3.123

Calculation:

 5 2/3+ 0.73 - 3.123

⇒ 17/3 + 0.73 - 3.123

⇒ 17/3 - 2.393

⇒ 5.667 - 2.393

⇒ 3.273

∴ The required result = 3.273 or 3.27

Given:

The speed of train which leaves station A = 50 km/hr

The speed of train which leaves station B = 150 km/hr

The distance between the two stations A and B = 725 km

Formula used:

Distance = Speed × Time

Relative Speed ( in opposite direction) = Speed I + Speed II

Meeting Time = Distance between the trains/ Relative Speed

Solution:

Relative speed of both the trains going in opposite direction = 50 km/h + 150 km/h

⇒ 200 km/h

Distance between the trains after half an hour of train leaving station A = 725 km - 50 km/h × 1/2 hours = 700 km

Meeting time = 700 km / 200 km/h = 7/2 hours

∴ Distance from station A where two trains are to meet = 25 km + 50 km/h × 7/2 hours = 200 km
