Question : A certain amount grows at an annual interest rate of 12% per annum, compounded monthly. Which of the following equations can be solved to find the number of years, $y$. That it would take for the investment to increase by a factor of 64?
Option 1: $64=(1.01)^{12y}$
Option 2: $\frac{1}{64}=(1.04)^{12y}$
Option 3: $64=(1.04)^{12y}$
Option 4: $8=(1.01)^{6y}$
Correct Answer: $64=(1.01)^{12y}$
Solution : Given: Rate of interest = 12% per annual = 1% per month Time = $12y$ months Using the given formula, Amount = P(1 + $\frac{R}{100})^n$, where P is principal, $R$ is the rate of interest per term for $n$ terms. ⇒ 64P = P(1 +
Question : Directions: In each of the following question, which one set of letters when sequentially placed at the gaps in the given letter series shall complete it? LU_ TUPLUBTU _ L UBT _ P _UBTUP
Option 1: BPUL
Option 2: BUPL
Option 3: LBPU
Option 4: PBUL
Correct Answer: BPUL
Solution : Given: LU_ TUPLUBTU _ L UBT _ P _UBTUP
To fill the series we have to divide the series – LU_ TUP/LUBTU _/ L UBT _ P/ _UBTUP Let's check the options – First option: BPUL; LUBTUP/LUBTUP/LUBTUP/LUBTUP
Question : I is the incentre of $\triangle \mathrm{ABC}$ of $\angle \mathrm{A}=46°$, then $\angle \mathrm{BIC}=$?
Option 1: 93°
Option 2: 113°
Option 3: 124°
Option 4: 134°
Correct Answer: 113°
Solution : In $\triangle$BIC Angle at incentre = 90° + $\frac{1}{2}$ × vertex angle ⇒ $\angle$BIC = 90° + $\frac{46°}{2}$ = 90° + 23° = 113° Hence, the correct answer is 113°.
Question : As we go from the Equator to the North Pole value of 'g', the acceleration due to gravity
Option 1: remains same
Option 2: decreases
Option 3: increases
Option 4: None of the above
Correct Answer: increases
Solution : The correct option is increases.
When moving from the equator towards the pole, the acceleration due to gravity (g) increases. This is because the Earth is not a perfect sphere but rather slightly flattened at the poles and bulging at the equator. The centrifugal force
Question : The following sentence has been divided into parts. One of them may contain an error. Select the part that contains the error from the given options.

Question : Directions: In the following question, select the related number from the given alternatives. 19 : 568 :: 25 : ?
Option 1: 748
Option 2: 623
Option 3: 799
Option 4: 654
Correct Answer: 748
Solution : Given: 19 : 568 :: 25 : ?
Like, 19 : 568→(19 × 30) – 2 = 570 – 2 = 568 Similarly, for 25 : ?→(25 × 30) – 2 = 750 – 2 = 748
So, 25 is related to 748. Hence, the
