Question : The average of P1, P2, and P3 is 50. If the value of P1 is half of the average, then what is the average of P2 and P3?
Option 1: 55
Option 2: 57.5
Option 3: 63.5
Option 4: 62.5
Correct Answer: 62.5
Solution : Average = $\frac{\text{Sum of values}}{\text{Number of values}}$ ⇒ $\frac{P1 + P2 + P3}{3}$ = 50 ⇒ P1 + P2 + P3 = 150 Since P1 is half of the average, P1 = 25 ⇒ 25 + P2 + P3 = 150 ⇒ P2 + P3
Question : Find the three consecutive numbers such that twice the first, three times the second and four times the third together make 191.
Option 1: 19, 20 and 21
Option 2: 21, 22 and 23
Option 3: 20, 21 and 22
Option 4: 21, 23 and 24
Correct Answer: 20, 21 and 22
Solution : Let the three consecutive numbers be $x, x+1$ and $x+2$. $⇒ 2x + 3(x+1) + 4(x+2) = 191$ $⇒ 2x + 3x + 3 + 4x + 8 = 191$ $⇒ 9x + 11 = 191$ $⇒ 9x = 180$ $⇒ x
Question : A man takes 6 hours to go to a place and come back by walking both ways. He could have saved 2 hours by riding both ways. The distance covered in the whole journey is 20 miles. What is the average speed for the whole journey if he goes by walking and comes back by riding?
Option 1: 8 miles/hr
Option 2: 5 miles/hr
Option 3: 6 miles/hr
Option 4: 4 miles/hr
Correct Answer: 4 miles/hr
Solution : We know, Average speed = $\frac{\text{Total distance}}{\text{Total time}}$ Time has taken on walking both ways at constant speed = 6 hours Time has taken on walking one way at constant speed = $\frac{6}{2}$ = 3 hours He gained 2 hours by riding both ways.
Question : Directions: In a certain code language, SHOE is written as 47. How will HELMET be written in that language?
Option 1: 63
Option 2: 83
Option 3: 68
Option 4: 72
Correct Answer: 63
Solution : Given: SHOE is written as 47.
Add the positional values of the letters of SHOE to obtain the required code. SHOE; S→19; H→8; O→15; E→5; 19 + 8 + 15 + 5 = 47 Thus, SHOE is coded as 47. Similarly, follow the same pattern
Question : A businessman bought an article and sold it at a loss of 5%. If he had bought it for 10% less and sold it for Rs. 33 more, he would have had a profit of 30%. The cost price of the article is:
Option 1: Rs. 330
Option 2: Rs. 155
Option 3: Rs. 150
Option 4: Rs. 300
Correct Answer: Rs. 150
Solution : Here CP denotes cost price and SP denotes selling price. Let CP = Rs. $x$ SP = $x(\frac{100-Loss\%}{100})$ ⇒ SP = $x(\frac{100-5}{100})$ ⇒ SP = $x(\frac{95}{100})$ New CP = $x-\frac{10}{100}x$ ⇒ New CP = $\frac{90}{100}x$ and new SP = $\frac{95}{100}x+33$ Profit = 30% New
