Given: 68, 68, 102, 204, 510, ?
The logic follows here is:

Thus, the missing number is '1530'
Hence, the correct answer is "1530".

Calculation:
Let B = B
A = B - 20% of B = 0.8B
C = A + 30% of A = 1.3A = 1.3 × 0.8B = 1.04B
New B = B - 20% of B = 0.8B
New C = C + 10% of C = 1.1C = 1.1 × 1.04B = 1.144B
Percentage increase of new C over new B =  1.114B - 0.8B/0.8B x 100
1. 144B = 0.8B/0.8B x 100 
⇒ 0.344B/0.8B x 100 
⇒ 0.344/0.8 x100 
⇒ 0.43 x 100 
⇒ 43%
∴ The correct answer is 43%.

∴ The correct answer is 1% decrease

Given:

Price of one quality of rice = Rs. 42/kg

Price of quality of rice = Rs. 50/kg

Quantity of other quality of rice = 7.5 kg

S.P pf the mixture = Rs. 53.10

Gain = 18%

Formula used:

C.P = S.P × [100/(100 + gain%)]

Calculation:

C.P of mixture = Rs. (53.10/118) × 100

⇒ Rs. 45

Let the quantity of rice costing Rs. 42 per kg be x kg

Now, as per the alligation method

(50 – 45) : (45 – 42) = x : 7.5

⇒ 5 : 3 = x : 7.5

⇒ x = 2.5 × 5

⇒ 12.5 kg

∴ The quantity of rice costing Rs. 42 per kg is 12.5 kg

Given:

Time taken by A to fill the tank = 5 hrs

Time taken by B to fill the tank = 10 hrs

Time taken by C to fill the tank = 12 hrs

Concept used:

Two inlet pipe alone can fill the tank in ‘A’ hours and ‘B’ hours respectively time taken by pipes together to fill the tank is ‘T’ hours can be calculated as :

(1/A) + (1/B) = 1/T

Calculations:

Time taken by A to fill the tank = 5 hrs

⇒ A’s one hour work = 1/5

Time taken by B to fill the tank = 10 hrs

⇒ B’s one hour work = 1/10

Time taken by C to fill the tank = 12 hrs

⇒ C’s one hour work = 1/12

∴ Time taken by them to complete the work

⇒ (1/A) + (1/B) + (1/C) = (1/5) + (1/10) + (1/12) = 23/60

According to question

⇒ (1/A) + (1/B) + (1/C) + (1/D) = 1/2

⇒ (23/60) + (1/D) = 1/2

⇒ 1/D = 1/2 – 23/60 = 7/60

∴ D alone can fill the tank in 60/7 hours

⇒ D can fill 3/4 tank in = (3/4) × (60/7) = 45/7

Alternate Method
Given:

A can fill the tank in 5 hrs

B can fill the tank in 10 hrs

C can fill the tank in 12 hrs

When D is also opened with all three pipes than the tank is filled in 2 hrs

Calculation:

LCM of 5, 10, 12 = 60

Efficiency of A = 60 / 5 = 12 units/hr

Efficiency of B = 60 / 10 = 6 units/hr

Efficiency of C = 60/12 = 5 units/hr

Total efficiency when A + B + C work together = (12 + 6 + 5) = 23 units/hr

According when A, B, C, D work together than the tank is filled in 2 hrd

So, Efficiency of A + B + C + D = 60 / 2 = 30 units/hr

⇒ Efficiency of D = Efficiency of A + B + C + D - efficiency A + B + C

⇒ Efficiency of D = 30 -23 = 7 units/hr

According to question

¾ × of work = ¾ × 60 = 45 units

Time taken by D alone to fill 45 units = (45 / 7) hrs

Given:

X, Y and Z invest capitals in the ratio 18 ∶ 20 ∶ 25.

After 6 months, X increases his capital by and Y decreases his capital by 50%, and no change in the capital of Z.

The profit is Rs. 15.25 lakhs at the end of the year.

Concept used:

1. Profit in a partnership business is always distributed in the ratio of capital investment.

2. ​

Calculation:

So, the new ratio of their investment on the annual basis

⇒ {(18 × 6) + (18 + 18 × 1/3) × 6} : {20 × 6 + (20 - 20 × 50%) × 6} : (25 × 12)

⇒ 252 : 180 : 300

⇒ 21 : 15 : 25

Now, the Y's share of the profit

⇒ 15.25 lakhs × 15/(21 + 15 + 25)

⇒ 3.75 lakhs = Rs. 3,75,000

∴ The share of Y in the profit of Rs. 15.25 lakhs at the end of a year is Rs. 3,75,000.

Given:

The average monthly expenditure of a family was Rs. 20,000 during the first three months.

The average monthly expenditure of a family was Rs. 25,500 during the next four months.

The average monthly expenditure of a family was Rs. 32,000 during the last five months.

Total savings during the year was Rs. 1,28,000

Concept used:

Income = Expenditure + Savings

Calculation:

Total expenditure over a year = 20000 × 3 + 25500 × 4 + 32000 × 5

⇒ 60000 + 102000 + 160000

⇒ Rs. 322000

Total income of the family over a year = 322000 + 128000

⇒ Rs. 450000

So, the average monthly income of the family = 450000 ÷ 12

⇒ Rs. 37500

Now,

40% of the average monthly income of the family = 37500 × 40%

⇒ Rs. 15000

∴ 40% of the average monthly income of the family (in Rs.) was Rs. 15000.

Logic : Alternately (6) and then (4) is added to the position value according to the English alphabetic series.
