Question : Directions: Rohan walks a distance of 3 km towards the north, then turns to his left and walks for 2 km. He again turns left and walks for 3 km. At this point, he turns to his left and walks for 3 km. How far is he from the starting point?
Option 1: 5 km
Option 2: 3 km
Option 3: 2 km
Option 4: 1 km
Correct Answer: 1 km
Solution : Firstly, we will draw the diagram as per the given instructions – Now, we have to find the distance between starting and endpoints.
In the above figure, O is the starting point and D is the finishing point. So, OD is the distance from
Question : Directions: Which of the following numbers will replace the question mark (?) in the given series? 29, 33, ?, 113, 369
Option 1: 55
Option 2: 51
Option 3: 54
Option 4: 49
Correct Answer: 49
Solution : Given: 29, 33, ?, 113, 369
The pattern is as follows – 29 + (2)2 = 29 + 4 = 33 33 + (2 × 2)2 = 33 + (4)2 = 33 + 16 = 49 49 + (2 × 4)2
Question : The graphs of the equations 7$x$ + 11$y$ = 3 and 8$x$ + $y$ = 15 intersect at the point P, which also lies on the graph of the equation:
Option 1: 2$x$ + $y$ = 2
Option 2: 2$x$ - $y$ = 1
Option 3: 3$x$ + 5$y$ = 1
Option 4: 3$x$ + 2$y$ = 3
Correct Answer: 3$x$ + 5$y$ = 1
Solution :
Equation of straight lines are following $7x + 11y = 3$..............................(i) And $8x + y = 15$............................(ii) On applying (i) × 1 – (ii) × 11, we get $(7x + 11y) - (8x + y) × 11 = 3 - 15
Question : In $\triangle$ABC, D and E are points on the sides BC and AB, respectively, such that $\angle$ACB = $\angle$ DEB. If AB = 12 cm, BE = 5 cm and BD : CD = 1 : 2, then BC is equal to:
Option 1: $8 \sqrt{3}$ cm
Option 2: $5 \sqrt{5}$ cm
Option 3: $6 \sqrt{5}$ cm
Option 4: $6 \sqrt{3}$ cm
Correct Answer: $6 \sqrt{5}$ cm
Solution : Given that $\angle ACB = \angle DEB$, we can say that $\triangle ABC$ and $\triangle DBE$ are similar by the Angle-Angle (AA) criterion of similarity. The ratio of corresponding sides in similar triangles is equal. $⇒\frac{AB}{DB} = \frac{BC}{BE}$ Given that AB = 12
Question : Suresh and Anil are working on a special project. Suresh takes 5 hours to type 40 pages and Anil needs 6 hours to type 32 pages on a computer. How much time will it take them to type a 110-page assignment if they work on two different computers?
Option 1: 8 hours 15 minutes
Option 2: 8 hours
Option 3: 7 hours 35 minutes
Option 4: 8 hours 40 minutes
Correct Answer: 8 hours 15 minutes
Solution : Pages typed by Suresh in one hour = $\frac{40}5 = 8$ pages Pages typed by Anil in one hour = $\frac{32}6$ = $\frac{16}3$ pages Pages typed by Suresh and Anil in one hour = $8 + \frac{16}{3} = \frac{40}3$ pages Time taken
Question : A shopkeeper marks an article at such a price that after giving a discount of $12 \frac{1}{2} \%$ on the marked price, he still earns a profit of 15%. If the cost price of the article is Rs. 385, then the sum of the marked price and the selling price (in Rs.) of the article is:
Option 1: 948.75
Option 2: 849.5
Option 3: 984.75
Option 4: 954.75
Correct Answer: 948.75
Solution : Let the marked price as MP and the selling price as SP. Given that the shopkeeper earns a profit of 15%, the selling price SP is 115% of the cost price. ⇒ SP = 1.15 × CP = 1.15 × 385 = Rs. 442.75 Also,
