Question : The difference between the simple interest and the compound interest at the same rate for INR 32,000 for 2 years is 80. What is the rate of interest, if in the case of compound interest, interest is compounded annually?
Option 1: 8% per annum
Option 2: 2% per annum
Option 3: 5% per annum
Option 4: 12% per annum
Correct Answer: 5% per annum
Solution : Principal amount = 32,000 Time = 2 years Let R be the rate of interest per annum. The difference between the simple interest and the compound interest = 80 Difference = $\frac{\text{P}\times{\text{R}}^2}{100^2}$ 80 = $\frac{(32000 × \text{R}^2)}{100^2}$ ⇒ R2 = 25 Rate
Question : If the sum of the diagonals of a rhombus is $L$ and the perimeter is $4P$, find the area of the rhombus.
Option 1: $\frac{1}{4}\left(\mathrm{~L}^2-\mathrm{P}^2\right)$
Option 2: $\frac{1}{2}\left(\mathrm{~L}^2-4 \mathrm{P}^2\right)$
Option 3: $\frac{1}{4}\left(\mathrm{~L}^2+3 \mathrm{P}^2\right)$
Option 4: $\frac{1}{4}\left(\mathrm{~L}^2-4 \mathrm{P}^2\right)$
Correct Answer: $\frac{1}{4}\left(\mathrm{~L}^2-4 \mathrm{P}^2\right)$
Solution : Perimeter = $4P$ ⇒ 4 × side = $4P$ ⇒ Side = $P$ Let $d_1$ and $d_2$ be the diagonals. The sum of the diagonals = $L$ ⇒ $d_1+d_2$ = L ----------------------(i) Now, (Side)$^2$ = $(\frac{d_1}{2})^2 + (\frac{d_2}{2})^2$ ⇒ $P^2 = (\frac{d_1}{2})^2 + (\frac{d_2}{2})^2$

Option 1: $\frac{3}{2}$
Option 2: $\frac{4}{5}$
Option 3: $\frac{1}{3}$
Option 4: $\frac{2}{3}$
Correct Answer: $\frac{2}{3}$
Solution : Percentage of water in the first mixture = 50% Percentage of water in the second mixture = 29% Percentage of water in final mixture = 36% Ratio = (36 – 29)% : (50 – 36)% = 7 :14 = 1 : 2 Total quantity =
