Question : If the amount on a certain principal in 3 years at a 12% rate of interest compounded annually is Rs. 12,000, what will be the amount (in Rs.) after the 4th year?
Option 1: 14,330
Option 2: 15,440
Option 3: 13,440
Option 4: 14,550
Correct Answer: 13,440
Solution : We have, $A = 12000, r = 12\%, n = 1 $ (compounded annually) and $t = 3$ years. $A = P \left(1+\frac{r}{100}\right)^{t}$ Substituting the given values into the formula, $⇒12000 = P (1+\frac{12}{100})^{1×3}$ $⇒12000 = P (1.12)^{3}$---(i) For $t = 4$ year $⇒ A

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
