Question : The marked price of an article is 150 percent of the cost price. If a 20 percent discount is given, then what will be the profit percentage?
Option 1: 20 percent
Option 2: 12.5 percent
Option 3: 25 percent
Option 4: 10 percent
Correct Answer: 20 percent
Solution : According to the question, Marked Price = 150% of cost price $\therefore$ $\text{MP} = 1.5\text{C}$ After a 20% discount, the selling price (SP) is given by: SP $=$ Marked Price $−$ Discount ⇒ SP $=1.5\text{C}−0.2\times1.5\text{C}=1.2\text{C}$ ⇒ Profit $=$ SP $−$ CP $=1.2\text{C}−\text{C}=0.2\text{C}$ Profit Percentage = $\frac{\text{Profit}}{\text{Cost Price}}\times 100$ $=\frac{0.2\text{C}}{C}\times 100$% ⇒ Profit Percentage = 20% Hence, the correct answer is 20 percent.
Question : If (2, 0) is a solution of the linear equation $2x+3y = k$, then the value of $k$ is:
Option 1: 6
Option 2: 5
Option 3: 2
Option 4: 4
Correct Answer: 4
Solution : Given: $2x+3y=k$ If (2, 0) is a solution of the linear equation $2x+3y=k$ Putting $x = 2$ and $y = 0$ to get: ⇒ $2(2)+3(0) = k$ $\therefore k = 4$ Hence, the correct answer is 4.
Question : Planck's Constant has the dimensions of:
Option 1: Energy
Option 2: Linear momentum
Option 3: Angular momentum
Option 4: Force
Correct Answer: Energy
Solution : The correct answer is Energy.
Planck's constant (ℎ) has dimensions of energy multiplied by time. In terms of units, it is commonly expressed in joule-seconds (J·s) in the International System of Units (SI). It can be expressed as [ℎ] = [E] × [t] where:
[ℎ} is the dimension of Planck's Constant, [E] is the dimension of energy, [t] is the dimension of time.

Question : Non - alignment basically implies:
Option 1: choosing its own policy
Option 2: neutrality towards power blocks
Option 3: bringing peace and unity to the world
Option 4: being a third world power
Correct Answer: neutrality towards power blocks
Solution : The correct answer is neutarilty towards power blocks.
Non-alignment movement was started by Indian Prime Minister Jawahar Lal Nehru, President of Egypt Gamal Abdel Nasser and others. Non alignment means not aligning with any of the power blocks which emerged after the second World War. In the aftermath of second World War, the world was ideologically divided into two power blocks led by USA and USSR. The newly independent nations at that time decided to maintain political neutrality and not to align with any of the power blocks and to maintain their sovereignty.

Option 1: 4
Option 2: 9
Option 3: 3
Option 4: 13
Solution : The prime factors of 76050 are 2, 3, 5, and 13. 76050 = 21 × 32 × 52 × 132 So, 76050 is not divisible by 4 out of the given options. Hence, the correct answer is 4.
Question : In our country the 'Van Mahotsav' day is observed on
Option 1: 10th August
Option 2: 1st July
Option 3: 2nd October
Option 4: 1st December
Correct Answer: 1st July
Solution : The correct answer is 1st July.

Question : P, Q, and R are partners and invest in a business. P invests $\frac{1}{5}^{th}$ of total investments and Q invests $\frac{1}{4}^{th}$ of the total investments. What is the ratio of investments of P, Q, and R respectively?
Option 1: 4 : 8 : 11
Option 2: 4 : 5 : 11
Option 3: 4 : 7 : 11
Option 4: 4 : 5 : 9
Correct Answer: 4 : 5 : 11
Solution : P invests $\frac{1}{5}$th of the total investment. Q invests $\frac{1}{4}$th of the total investment. Taking, LCM (4, 5) = 20 Let the total investment be Rs. 20 P invests $\frac{1}{5}$th of the total investment = $\frac{1}{5}\times 20$ = Rs. 4 Q invests $\frac{1}{4}$th of the total investment = $\frac{1}{4}\times 20$ = Rs. 5 Thus R invests = Rs. 20 – (Rs. 4 + Rs. 5) = Rs. 20 – Rs. 9 = Rs. 11 Thus the ratio of the profit of P, Q, and R respectively is 4 : 5 : 11. Hence, the correct answer is 4 : 5 : 11.
