If income of R is 30% more than the income of Q and the income of Q is 20% more than the income of P, then the income of R is how much percent more than the income of P?
Let income of P be x
The income of Q is 20% more than P
So income of Q = x + 20x/100 = 1.2x
The income of R is 30% more than Q.
So income of R = 1.2x + (30 × 1.2x)/100 = 1.56x
% difference in incomes of R and P = [(Income of R  Income of P)/Income of P] × 100%
= [(1.56x  x)/x] × 100% = 56%

In which of the following year was WhatsApp started?
A shopkeeper buys a fan for Rs 14500. For how much should he sell (in Rs) it to gain a profit of 10%?
Cost price = C.P = Rs. 14500
profit % = (profit/C.P) × 100
⇒ 10 = (profit/14500) × 100
Profit = (10 × 14500)/100 = 1450
Profit = S.P  C.P
S.P = sell price
⇒ S.P = profit + C.P = 1450 + 14500 = Rs. 15950
Shortcut method:
Profit = 10%
Selling price = (1 + profit percent/100) × cost price
Selling price = (1 + 10/100) × 14500 = 1.1 × 14500 = Rs.15950

The coordinates of the centroid of a triangle ABC are (2, 2). What are the coordinates of vertex C if coordinates of A and B are (7, 1) and (1, 2) respectively?
Let the coordinate of C be (x, y)
Centroid of triangle can be given as
For X coordinate,
⇒ 2 = (x + 7 + 1)/3
⇒ x = 2
For Y coordinate,
⇒ 2 = (y  1 + 2)/3
⇒ y = 5
∴ The coordinate of C is (2, 5)
If ‘A’ denotes ‘÷’, ‘B’ denotes ‘×’, ‘C’ denotes ‘+’, ‘D’ denotes ‘ ‘, then find the value of
68 C ((30 D 200) B 10) A 2?
Given: 68 C ((30 D 200) B 10) A 2
Substituting the symbols:
68 + ((30  200) × 10) ÷ 2
Solution through BODMAS:
68 + ((30  200) × 10) ÷ 2
68 + ((  1700) ÷ 2 =  782
Hence, the correct answer is  782.

In certain language, ‘pan’ tan san' means 'pen is gold’, 'tan san van' means 'gold is old', 'san van kan' means ‘old is bold’, 'kan san haw' means ‘bold is strong’. How is 'strong is pen' coded in that language?
'pan' → pen
'san' → is
'haw' → strong
So, 'strong is pen' is coded as ' pan haw san'.
Therefore, ‘pan haw san' is the correct answer.
Read the given question and decide which of the following argument is/are strong.
Should all indirect taxes in India be combined into a single tax on all commodities?
Arguments:
1. Yes, this will considerably simplify the tax collection mechanism and the cost of collection of taxes will also reduce.
2. No, no other country has adopted such system.
Only 1^{st} argument is strong as it provides very convincing information in favour of a single tax system for commodities. The 2^{nd} argument does not hold strong as it does not provide enough information. No other country adopting this system of taxation does not mean that it is not a profitable venture.

Which of the following planet is not a terrestrial planet?
What is the value equation a^{3} + b^{3} + c^{3}  3abc if a^{2} + b^{2} + c^{2} = ab + bc + ca + 4 and a + b + c = 4.
As we know, (a^{3} + b^{3} + c^{3} – 3abc) = (a + b + c)(a^{2} + b^{2} + c^{2} – ab – bc – ca)
Given, a^{2} + b^{2} + c^{2} = ab + bc + ca + 4
⇒ a^{2} + b^{2} + c^{2} – ab – bc – ca = 4
∴ (a^{3} + b^{3} + c^{3} – 3abc) = 4 × 4 = 16

What will come in place of question mark ‘?’ in the following question?
13 × (22 + 3)  3 × (15  5)^{2}  15 = ? × 5
Follow BODMAS rule to solve this question, as per the order given below.
Step  1  steps of an equation enclosed in ‘Brackets’ must be solved first.
Step  2  any mathematical ‘Of’ or ‘Exponent’ must be solved next.
Step  3  Next, the parts of the equation that contain ‘Division’ and ‘Multiplication’ are calculated.
Step  4  Last but not least, the parts of the equation that contain ‘Addition’ and ‘Subtraction’ should be calculated.
Now, the given expression:
⇒ 13 × (22 + 3)  3 × (15  5)^{2}  15 = ? × 5
⇒ 13 × 25  3 × (10)^{2}  15 = ? × 5
⇒ 13 × 25  3 × 100  15 = ? × 5
⇒ 325  300  15 = ? × 5
⇒ ? × 5 = 25  15
⇒ ? = 10/5
